Parasitology and Food Safety: Understanding Contamination and Prevention in Restaurants for Biology Students

Parasitology, the study of parasites, might not be the first thing that comes to mind when you bite down hard on a tasty burger or dig into a fresh salad at a restaurant. But for biology students, it is essential to learn how they get into food so that they can understand its safety. Parasites are organisms that inhabit or live within a host, typically causing harm. In restaurants, they can contaminate food, which is serious to health. This article breaks down how parasites get into restaurant food, the dangers they pose, and practical ways to stop them.

Parsites In Food

How Parasites Contaminate Restaurant Food

Parasites don’t appear out of nowhere — they hitch a ride through specific channels. Learning how this happens is crucial, and studying restaurant management can offer insights into handling food safely. Raw or undercooked ingredients, unsanitary conditions, and contaminated water are the most likely suspects. Let’s take a look at how this happens.

First, raw meat, fish, and vegetables are prime targets. Take pork, for example—parasites like Taenia solium (the pork tapeworm) can hide in undercooked meat. Fish, especially in sushi restaurants, can be contaminated with Anisakis, a worm that calls raw seafood home. Even vegetables aren’t safe, Toxoplasma gondii can cling to produce if it’s been rinsed in contaminated water. 

Second, people handling food can spread parasites.  If the cook doesn’t wash their hands after coming into contact with raw meat, Entamoeba histolytica can get into your food. Finally, water used for cooking or cleaning can harbor Giardia lamblia if it’s not properly treated.

Here’s a quick list of common parasites in restaurant settings:

  • Taenia solium – Pork tapeworm from undercooked pork.
  • Anisakis – Found in raw or undercooked fish.
  • Toxoplasma gondii – Lives on unwashed vegetables or meat.
  • Giardia lamblia – Spread through contaminated water.
  • Entamoeba histolytica – Transferred via poor hygiene.

Why Parasites Are a Big Deal

Parasites aren’t just gross—they’re dangerous. When you eat contaminated food, these organisms can take up residence and settle in comfortably inside you, causing everything from minor stomach aches to potentially deadly diseases. Giardia, for example, leads to diarrhea and cramps, whereas Toxoplasma harms unborn babies if the mother-in-waiting becomes infected. In restaurants, where dozens of meals are being made daily, one error can spark an outbreak.

The numbers back it up. The CDC estimates that foodborne diseases, including parasites, infect 48 million Americans annually. Not all of those are parasitic, but Toxoplasma infection alone affects over a million people yearly in the United States. For biology students, it helps to clarify how parasites exploit food systems—and why it matters to stop it.

How Restaurants Get It Wrong

Restaurants are not to blame every time, but mistakes do happen. Undercooking is a doozy—imagine a hectic kitchen cooking pork that’s still rosy in the middle. Cross-contamination is also an issue: using the same cutting board to cut pork and vegetables without sanitizing it spreads parasites at warp speed. 

Let’s not forget about sourcing—buying low-cost, uninspected meat or fruit and vegetables from suspect sources makes it more likely. Add staff who skip handwashing or use tap water from dodgy systems, and you’ve got a recipe for trouble.

Common restaurant slip-ups:

  • Undercooking meat or fish.
  • Reusing dirty cutting boards or knives.
  • Buying from unreliable suppliers.
  • Ignoring handwashing rules.
  • Using untreated water for cooking or washing.

Spotting Parasites in Food

You can’t see parasites with the naked eye, but there are indications of infestation. Infected fish might look off—discolored, or slimy. Infected pork might sometimes carry tiny cysts when you cut it open, but they’re hard to spot. Vegetables might not show you anything, but if they’re gritty or questionable, suspect the worst. In a restaurant, you’re relying on the kitchen to catch this, which is part of why training matters.

Laboratory work helps biology students. Microscopes reveal parasite eggs or larvae in samples. Giardia cysts, for instance, are small and oval-shaped and about 10 micrometers long. Getting to identify those in class gives one an advantage in the field.

Prevention: Keeping Parasites Out

The prevention of parasites starts with good hygiene. Restaurants can—and should—be strict about regulations for safeguarding food. Biology students can learn from this, too; it’s applied science in action.

  • Cook it right. Parasites are killed by heat. Ground pork needs to hit 160°F (71°C) in the center to destroy Taenia solium. Fish needs to reach 145°F (63°C) to destroy Anisakis. No guessing—use a thermometer.
  • Clean everything. Tools, hands, fruits, and vegetables have to be scrubbed. Hot soapy water for knives and cutting boards; clean water for vegetables. They hate cleanliness.
  • Source smart. Buy from solid suppliers who test for parasites. Cheap meat might save money, but it costs in terms of health.
  • Water safety. Employ treated or filtered water. Giardia thrives in contaminated streams, not clean taps.
  • Train staff. Teach employees about parasites and hygiene. A 5-minute handwashing lesson can avert an outbreak.

Prevention checklist for restaurants:

  • Cook meat and fish to safe temperatures.
  • Clean all surfaces and tools between uses.
  • Source ingredients from reputable vendors.
  • Use safe, treated water.
  • Educate staff on parasite risks.

What Biology Students Can Do

You’re not only studying this for exams—parasitology comes together with real life. Enter a restaurant kitchen (with permission) and see what their routine is. Ask: Do they check meat temperatures? How do they wash greens? Compare it to what you’ve learned. You may even analyze water samples in a lab for Giardia or examine meat under a microscope for cysts. It’s hands-on biology that comes together with food safety.

And think big. Learn how parasites can withstand cooking or being washed in dishwater. Toxoplasma survives some heat, which is why pregnant women will not eat rare meat. Share what you have learned—write about it, perhaps, or talk to someone who owns a local restaurant. You’ve got the knowledge they need.

The Bigger Picture

Restaurant parasites are not a biology problem—they are a public health problem. Outbreaks are costly, shut down businesses, and sicken people. Prevention saves more than just health alone—it keeps the food industry in business.

To students, this is a call to action. Parasitology is not abstract; it is in the food you eat. Studying contamination and prevention makes your studies relevant to the real world. The next time you’re in a restaurant, you’ll know what’s at stake—and how to make it safe.

Final Thoughts

Parasitology and food safety are just a match made in heaven, especially in restaurants. From Taenia in pork to Giardia in water, parasites find their way in through sloppy mistakes. But with proper cooking, cleaning, and sourcing, they’re beatable. Biology students can take this information, apply it, and make a difference. So, study hard, ask questions, and maybe even keep your favorite diner parasite-free. It’s science that matters—one plate at a time.

Understanding Human Development Across the Lifespan



Human development is a fascinating and multifaceted process that spans from birth to late adulthood. It encompasses physical, cognitive, emotional, and social changes that occur over time. Understanding the stages of human development is crucial for professionals, educators, and caregivers, as it allows them to support individuals at various life stages effectively.

By delving into the intricate patterns of growth and behavior, we can better comprehend the factors that shape us into who we are today.

The Foundations of Human Development

Human development begins at conception, where genetic and environmental factors interact to set the stage for growth. During infancy and early childhood, significant milestones occur, such as language acquisition, motor skill development, and emotional bonding.

These early years are critical for establishing a foundation for future learning and behavior. The physical growth experienced during this period, combined with cognitive advancements, illustrates how interdependent various aspects of development are.

Emotional and social development also play a key role during these early stages. Attachment to caregivers fosters a sense of security, which influences how children interact with their environment and form relationships later in life. Understanding the importance of these early experiences helps professionals guide families and create supportive environments for children.

Advancing Knowledge Through Specialized Studies

To delve deeper into understanding human behavior and development, many opt to pursue specialized education. A bachelor of psychology online equips students with insights into human behavior, mental health, and cognitive processes.

This flexible option allows learners to explore developmental psychology, learning theories, and behavioral patterns, all while accommodating diverse schedules and commitments. This pathway not only broadens academic horizons but also prepares individuals for roles that demand an in-depth understanding of human development.

The study of psychology reveals how internal and external factors influence growth across the lifespan. From childhood experiences to societal influences, these insights shape how we perceive and interact with the world. This knowledge becomes invaluable in professions such as counseling, social work, and education, where understanding individual differences and developmental needs is paramount.

Exploring Cognitive Growth and Behavior

Cognitive development involves the progression of thinking, reasoning, and problem-solving abilities. Jean Piaget’s stages of cognitive development remain a cornerstone for understanding how children’s thought processes evolve over time.

From the sensorimotor stage in infancy, where learning occurs through sensory experiences and actions, to the formal operational stage in adolescence, where abstract reasoning emerges, cognitive growth is both structured and dynamic.

During adolescence, critical changes occur as individuals navigate the transition from childhood to adulthood. The teenage years are marked by increased independence, identity exploration, and heightened emotional experiences. These changes often coincide with challenges related to peer influence, academic demands, and self-discovery.

Social and Emotional Changes Across Adulthood

Adulthood encompasses a wide range of developmental changes that often differ based on life circumstances. Early adulthood typically focuses on establishing careers, relationships, and personal goals.

The pursuit of independence, stability, and self-fulfillment characterizes this stage. Emotional resilience and adaptability are crucial as individuals face responsibilities such as career challenges, parenthood, and societal expectations.

As individuals enter middle adulthood, priorities may shift toward maintaining relationships, mentoring younger generations, and reassessing personal achievements. Physical changes, such as the gradual decline in strength and vitality, may also occur, prompting a focus on health and well-being.

Late adulthood, often referred to as the golden years, brings its own set of challenges and opportunities. Retirement, changes in family dynamics, and coping with physical aging require emotional strength and adaptability. This period also offers a chance for reflection, legacy building, and the nurturing of
meaningful connections.

Cultural and Environmental Influences on Development

Culture and environment profoundly shape human development, influencing everything from values and beliefs to educational opportunities and societal roles. For instance, cultural practices surrounding parenting, education, and aging differ widely across societies, demonstrating the adaptability of human behavior to diverse contexts.

Environmental factors such as socioeconomic status, access to healthcare, and exposure to supportive networks also play a pivotal role in shaping developmental outcomes. Recognizing these influences enables professionals and communities to address disparities and provide resources that foster growth and resilience.

The Role of Lifelong Learning in Human Development

Human development does not cease with adulthood; rather, it continues as individuals acquire new skills, adapt to changing circumstances, and pursue personal growth. Lifelong learning becomes essential in maintaining cognitive flexibility, emotional well-being, and a sense of purpose. Whether through formal education, hobbies, or interpersonal relationships, continuous learning enriches life at every stage.

The later years of life highlight the importance of staying socially connected and mentally active. Activities that promote cognitive engagement, such as reading, problem-solving, and engaging in meaningful conversations, contribute to overall well-being and help mitigate the effects of aging.

Addressing Challenges Across the Lifespan

Every stage of human development presents unique challenges that require tailored approaches to support. Childhood may involve addressing developmental delays, adolescence brings mental health concerns, and adulthood often requires balancing work-life dynamics. In later years, challenges such as loneliness and health complications may arise.

By understanding these potential difficulties, professionals, families, and communities can create strategies to mitigate their impact. Early intervention, accessible resources, and fostering supportive relationships are all critical components of addressing these challenges effectively.

All in all, human development is a lifelong journey influenced by a combination of genetic, environmental, cultural, and individual factors. From infancy to late adulthood, each stage brings new opportunities for growth, learning, and connection.

Gaining a comprehensive understanding of these processes equips us to support individuals and communities in achieving their fullest potential. Whether through professional insights gained from higher education or through active participation in nurturing relationships, every effort contributes to fostering a society that values growth and development at every stage.

Disclaimer: The information provided here is for educational purposes only and is not intended to diagnose, treat, or cure any medical conditions. Before incorporating any herbal remedies into your routine, it is recommended to consult with a healthcare professional, especially if you have existing health conditions or are taking medications.

Prostate wellness is crucial for maintaining overall health in men, especially as they age. Most men don’t think about their prostate health until problems arise. Taking proactive steps towards maintaining prostate health can reduce the risk of complications, including prostate cancer. By making lifestyle changes, focusing on dietary choices, and committing to regular screenings, men can significantly impact their prostate wellness.

For many, incorporating simple strategies such as engaging in regular physical activity and choosing a nutrient-rich diet are effective starting points. Regular check-ups and preventive screenings also play a vital role. Consulting healthcare professionals and exploring natural health resources like Ben’s Natural Health can provide further guidance and supplementation options.

Understanding the significance of these steps can empower individuals to take charge of their health. Proactive management not only promotes wellness but also offers peace of mind in preventing future issues. The following sections will detail ten essential steps that men can take to support their prostate health.

Key Takeaways

  • Proactive steps can reduce prostate health risks.
  • Lifestyle and diet changes are essential.
  • Regular screenings are vital for prevention.

Lifestyle and Dietary Adjustments for Prostate Health

Adopting specific lifestyle and dietary changes can significantly enhance prostate health. Important considerations include eating a balanced diet, staying active, maintaining a healthy weight, and managing stress.

Adopt a Prostate-Friendly Diet

A balanced diet rich in nutrients supports prostate health. Incorporating plenty of fruits and vegetables such as tomatoes and broccoli can provide antioxidants like lycopene, which are beneficial. Whole grains are also essential for fiber intake, which aids digestion.

Healthy fats are important, too. Sources such as omega-3 fatty acids found in fish like salmon support overall wellness. It’s wise to limit red meat and processed foods. Consumption of unhealthy fats should be minimized. Overall, nutrition plays a vital role in keeping the prostate healthy.

Incorporate Regular Physical Activity

Engaging in regular exercise promotes overall health and specifically benefits prostate wellness. Activities like walking, jogging, or cycling boost circulation and help regulate weight. Strength training is also beneficial as it can enhance muscle mass, supporting metabolic health.

Exercise contributes positively to hormonal balance and helps reduce risks associated with prostate issues. It is important to stay consistent with physical activity routines for the best results. People should aim for at least 150 minutes of moderate exercise weekly. This can include a mix of aerobic and strength-based workouts.

Maintain a Healthy Weight and Hydration Level

Achieving and maintaining a healthy weight is crucial for prostate health. Weight management can prevent inflammation and other health risks. A prostate-friendly diet aids in achieving this balance. Limiting alcohol consumption is advisable as excess intake can interfere with weight control efforts.

Good hydration is equally important. Drinking plenty of water helps in detoxification processes and keeps the body functioning optimally. Proper hydration supports kidney health and reduces strain on the urinary tract, which is beneficial for prostate health. Individuals should aim to drink about 8 cups of water daily, adjusting based on individual needs.

Manage Stress Through Mindfulness Practices

Stress management is essential for both mental well-being and physical health. Practices such as meditation, deep breathing, and yoga help reduce stress levels. These activities contribute to better hormonal balance and can decrease tension in the body.

Mindfulness practices have a calming effect and can enhance attention and emotional regulation. Regular engagement in stress-reducing techniques may support better prostate wellness. Incorporating just a few minutes of relaxation practices each day can help individuals handle stress more effectively and maintain overall health.

Preventive Screening and Supplementation

Taking care of prostate health is crucial for long-term wellness. Men should consider both regular screenings and thoughtful supplementation to maintain proper prostate function. These steps can aid in early detection and support overall health.

Understand and Perform Regular Prostate Screenings

Regular screenings for prostate health are essential. The digital rectal exam (DRE) and prostate-specific antigen (PSA) test are common methods. The DRE involves a physician checking the prostate for abnormalities. The PSA test measures levels of prostate-specific antigen in the blood. Elevated levels can indicate prostate problems like cancer or benign prostatic hyperplasia (BPH).

Starting screenings at age 50 is typical, but those with a family history may need to begin earlier. Early detection helps manage prostate enlargement and reduce cancer risk. Regular check-ups and consultations with a healthcare provider can personalize screening schedules based on individual risk factors. Screening plays a significant role in maintaining prostate health and preventing complications.

Consider Natural Supplements and Their Benefits

Natural supplements can support prostate health by reducing inflammation and improving urinary function. Saw palmetto and beta-sitosterol are popular choices. These can help alleviate symptoms of BPH. Stinging nettle and pygeum may also support hormone regulation and improve urinary flow.

Green tea and zinc are known for their anti-inflammatory properties, helping reduce prostatitis risk. Herbal supplements can be an effective way to maintain prostate wellness naturally. Exploring options like natural supplements may provide additional benefits. Always consult a healthcare professional before starting new supplements to ensure they are appropriate for individual health needs.

Conclusion

Ensuring prostate wellness involves a combination of healthy habits and lifestyle choices. Regular exercise, a balanced diet, and routine health check-ups play critical roles in maintaining prostate health.

It’s important to limit alcohol, avoid smoking, and stay informed about potential signs of prostate issues. Consulting with healthcare professionals can also provide tailored advice and support.

By incorporating these steps into daily life, individuals can promote better long-term prostate health.

8 Most Useful Bill Nye Videos To Watch

-Even if you are in college.

Bill Nye the Science Guy hasn’t produced new episodes since the end of Season 5 in 1998, but the show’s namesake host remains active in the promotion of science – and many of his videos remain outstanding content to watch even if you’re in College (or beyond).

Here at Biology Junction, our focus is on our own namesake subject, and that’s what this list focuses on – but for those of you who came here for a more general list, we’ve also included a few non-Biology videos down at the bottom. These videos are helpful regardless of what type of science you’re interested in, so everyone should take a look at them.

How We Chose These Videos

What good is a list without an explanation of how we made it? It wouldn’t be good science if we just threw it up here! Truth is, though, creating this list wasn’t very hard. First, we narrowed our list of sources to the best selections of Bill Nye videos – his classic show and the more-recent Greatest Discoveries series.

Next, we considered how useful each topic is to know. For students studying biology, it does no good to dive into topics more advanced than you’re ready for. Fortunately, most of Bill Nye’s videos are accessible even to beginners and provide a strong foundation for the topic. This ended up being a minor concern, but we were determined to go through the process.

Finally, we checked for the availability of videos. It doesn’t help to be told to watch a video if you can’t find it. A simple search should be enough to locate any of the videos on this list. If that fails, you should be able to get them from your library or preferred streaming service. We had a preference for videos that are freely available since budgets can be tight in college, but that didn’t significantly impact this list.

For our non-Biology videos, we used a similar process. Instead of emphasizing Biology, though, we decided to focus on the foundations of science and the information that’s most useful for everyone to know.

The Best Biology Videos From Bill Nye

Here are our top choices for Biology videos.

1: Biodiversity (S1 E9)

Biodiversity is the 9th episode of Bill Nye the Science Guy, and while it’s not the first to feature a Biology topic, we think it’s easily one of the most important episodes. This video focuses on more than just where things live – it also explains the concept of ecosystems and how important it is to have a variety of living things in each area.

Fish in the habitat

Arguably the most important lesson of this episode is understanding that ecosystems are far more complex than figuring out which living things eat each other. Each part of an ecosystem affects all of the other parts. That’s why we have to be so careful when introducing plants or animals to new habitats – if the ecosystem isn’t ready to handle it, the whole thing could collapse.

A second lesson to focus on is how ecosystems can vary in size – and, in many cases, overlap each other. The Great Barrier Reef has its own ecosystem, but it’s part of the larger Pacific Ocean – and from there, it ultimately affects all life on the planet (even if the impact isn’t obvious).

Understanding biodiversity is critical to understanding biology as a whole. Life does not exist in a vacuum – not unless we put it there, anyway. Environments affect life and vice versa, and if you want to understand why something is the way it is, you have to look at the bigger picture.

2: Cells (S1 E17)

cells

Cells are a fundamental component of life – and even if you think you understand them, it’s good to get a refresher on the topic before you start your studies. The main reason for this is that when we say something “affects an organ”, what we mean is “it affects certain cells of the organ in a particular way”.

For example, if you want to understand why too much alcohol can hurt the liver, you need to look at its impact on the cells of the liver. If you want to heal that liver when you’re done, you have to figure out what will encourage the cells to do that. Cells are the ultimate “micro” topic in biology, making the Bill Nye cells video easily one of the most important episodes for biologists to watch.

3: Food Web (S2 E6)

It’s hard to talk about biology without eventually talking about food – but how things get their food is a little more complicated. Only watch this video after you’ve watched Biodiversity, because that video provides some important groundwork for this topic.

The short version is that a food web describes how each part of an ecosystem gets its food. Ultimately, each living thing gets food either from other living things (like insects, plants, or rodents) or from the sun. Every living creature is ultimately dependent on plants – who, let’s not forget, are often nourished by the uneaten bodies of dead creatures.

(If you’re having flashbacks to a certain Disney movie about a young lion, there’s a reason for that – the Circle of Life, where living things depend on each other, is quite real.) Watch Food Web

4: Plants (S3 E3)

Given how important plants are to the previous video, now’s a good time to get a refresher on what they are, how they work, and what sort of impact they have on our lives. The crazy thing is how plants can synthesize their own food as long as they have sunlight, water, and carbon dioxide – though healthy soil and a few other nutrients certainly help.

plant

Plants are also important for their impact on other aspects of Biology. For example, many medicines are made from plants or plant by-products and affect certain living things in specific ways. Once we understand how something works, we can start figuring out the best way to make use of it.

This is particularly helpful if you’re looking for a job with biology. Most of your work will likely involve seeing how various inputs (types of food, situations, etc.) affect living things, and plants will be a part of that. Studying life alone is a limited topic – but there are endless possibilities when studying the way things affect life.

5: Populations (S3 E19)

Populations are a group of similar living things living in a set area. We often refer to the population of the human race, but we may also talk about the population of a specific city, voting district, or another region.

sunset with population

In biology, the most important thing is understanding the populations of other living things, how they’ve changed over time, and what’s caused them to do so. As you learned in videos like Biodiversity and Food Web, living things all affect each other – and a sudden rise or drop in one population will ripple across the ecosystem and begin affecting other creatures.

There may not be as many fancy names or scientific terms here, but it’s still worth watching this video to ensure you have a good grasp of the fundamentals of biology.

6: Biology – Greatest Discoveries

Finally, Bill Nye’s Greatest Discoveries video on Biology rounds out the best videos on this topic with a look at 13 of the most important discoveries in biology. This includes a discussion on the discovery and impact of:

  • Microorganisms like bacteria, blood cells, and sperm
  • The Cell Nucleus that functions at the center point of most cells
  • Archaea, microorganisms that lack a cell nucleus but aren’t quite like bacteria
  • Cell Division, the process of growth and, in many ways, life itself
  • Sex Cells and how they differ from most other types of cells
  • Cell Differentiation and how different types of cells are made
  • Mitochondria, which are separate from cells but provide a critical function for metabolizing chemicals
  • The Krebs Cycle, which is how protein, fats, and sugars are turned into energy
  • Neurotransmission, which centralizes the body’s ability to control itself
  • Hormones, which are far more complicated than teenage urges
  • Photosynthesis, a process where light is turned into chemical energy
  • Ecosystems, a quick look back at larger ecological units
  • Tropical Biodiversity, or why warm and sunny places tend to have a much greater variety of life

Together, all of these are important for biologists to know.

The Best Overall Science Videos From Bill Nye

Whether or not you’re focused on biology, these videos are helpful for improving your overall understanding of science and are worth watching at any age.

1: Pseudoscience (S4 E9)

Many things that sound like science but aren’t. These things are often called pseudoscience, and learning how to recognize them is a valuable skill for any scientist. Fortunately, the entire topic can be brought down to a few simple principles.

First, science involves testing claims and ideas. If somebody says something can’t be tested, then it’s not within the realm of science and shouldn’t be treated as such. In those cases, it’s okay to say “perhaps we’ll never know for sure”.

Second, extraordinary claims require extraordinary proof. In other words, the more important your claim is, the more you need to support it with verifiable evidence. As the person making a claim, it is your job to provide corresponding proof. It is not the job of others to demonstrate that you’re right.

Furthermore, your results should be reproducible. Proper science only happens when someone tries to prove you wrong – fairly, of course – and fails to do so. If you repeat an experiment and keep getting results, you don’t have any answers – just more questions to ask.

Finally, you should learn critical thinking. This graphic is especially helpful for that and provides many questions that help you uncover the truth. For example, when presented with a claim, you may want to figure out who benefits from it, what the best/worst case scenarios of it are, where it might be a problem or solution, what might make it unacceptable, why people might need it, and how to approach it safely.

In many cases, purveyors of pseudoscience are simply looking to profit from your ignorance. As a scientist, it is your duty to see past things like that and uncover the truth. Watch Pseudoscience now.

2: Measurement (S5 E17)

Coming in as one of the last episodes ever aired, Measurement is something that honestly should have been one of the first videos they made. Measuring things is critical to the foundations of science as a whole. Proper measurements provide objective, verifiable information using a common set of standards, and it’s impossible to overstate how important this is.

There are a few important things to learn from this video, Measurement.

First, there are many ways of measuring things. You can measure units (members of a population), dimensions (the size of something), time (how long it takes something to happen), effects (what happens), and many other topics.

Second, you’ll learn why things should be measured. It’s not just to expand the amount of information we have, though that’s valuable in and of itself. Instead, measurements help us understand what’s different about two subjects so we can proceed to uncover why and how that difference occurred.

Taken far enough, this can lead to discoveries, such as finding that one person in a neighborhood didn’t get sick because they ate a particular herb.

Measurements are almost never a focus in and of themselves – but they’re a vital part of most scientific activities. If you want to be a scientist, then you’re almost certainly going to do a lot of measurements over the course of your career. That makes this innocent-sounding video one of the most helpful episodes of Bill Nye.
