The Higgs Boson is awesome but it's NOT responsible for most of your mass! Thanks to audible.com for supporting this episode: http://bit.ly/ZJ5Q6z The Higgs mechanism is meant to account for the mass of everything, right? Well no, only the fundamental particles, which means that electrons derive their mass entirely from the Higgs interaction but protons and neutrons, made of quarks, do not. In fact the quark masses are so small that they only make up about 1% of the mass of the proton (and a similar fraction of the neutron). The rest of the mass comes from the energy in the gluon field. Gluons are massless, but there is so much energy in the field that by E=mc^2 there is a significant amount of mass there. This is where most of your mass comes from and the mass of virtually everything around you. Thanks to Professor Derek Leinweber for his great images, animations and explanations.

There is a gravitational force of attraction between the Earth and the moon, but is it mutual? That is, are the forces on the Earth and the moon equal? Most people would say no, the Earth exerts a greater force of attraction because it is larger and has more mass. This is a situation in which Newton's Third Law is relevant. Newton's Third Law says that for every force, there is an equal and opposite reaction force. So the force the Earth exerts on the moon must be exactly equal and opposite the force the moon exerts on the Earth. But how can that be - that the same size force keeps the moon orbiting, but barely affects the Earth? The answer is inertia - the tendency for all objects with mass to maintain their state of motion. Since the Earth has much more mass than the moon, it has greater inertia and therefore experiences much less acceleration for the same amount of force.

Can you find the mistakes? "I am student", "I am agree", "Yesterday, I'm go downtown", "He no have money", "I want to meet the downtown". If you don't know, this is the lesson for you! These are mistakes made by students of all levels, so watch this video and learn to avoid these common errors. Take the quiz here: http://www.engvid.com/dont-make-these-mistakes/ And don't forget to check out our other video on 5 common English learner mistakes: http://www.engvid.com/5-common-mistakes/ TRANSCRIPT Hey, everyone. I'm Alex. Thanks for clicking, and welcome to this lesson on five more common English learner mistakes. So if you have watched my other video on five common English learner mistakes, this is a follow up to give you five more. So let's not waste time and get right to it. Here we go with No. 1. So this first mistake is common because in many languages, when you discuss jobs or your station in life, you don't use articles even if you come from a country where there are articles in the language. So for example, "I am student." "He is engineer." If I ask you, "What do you do", you need to use an article because "student" is countable; it's singular; and "engineer' is countable and it's singular. So you have to say, "I am a student." "He is an engineer." Now, let's move on to No. 2. Okay. Here, we have two sentences on the board. We have, "I am agree." "Are you agree?" So in this situation, "agree" is a verb. We don't say, "I am agree." You can just say, "I agree." If it's negative, "I don't agree" or, "I disagree." And the question is not, "Are you agree?" It's, "Do you agree?" Now, if you are set on wanting to say "I am" and use "agree" in some way, you would have to say, "I am in agreement." This is very formal, but it is possible. Otherwise, you say, "I agree" or, "I disagree" and, "Do you agree?" Now, let's move on to No. 3. This next mistake is about the use of the past tense. For new English speakers, because they can't form the past tense, sometimes they use the verb "to be" with the verb. So I have heard, "I'm go downtown yesterday." Or, "He was see his cousin." If you are speaking in the past, make sure you simply use the past simple verb. In this situation, we don't say "I'm go". The past of "go" is "went". "I went downtown." We don't say "he was see". The past of "see" is "saw". So this is about using the past simple form of the verb to speak about the past. Never say "I'm go", "I'm do", "I'm make". "I saw"; "I made"; "I did"; "I played". Okay? Now, let's move on to No. 4. Now, this mistake is about using negatives. In many languages, whether they're European or Latin, Spanish, I hear this frequently. So you might hear, "He no have money" or, "They no like chocolate." So if you are making a sentence in the sent simple, and you want to make it negative, you have to use "doesn't" and "don't". So not "he no have" but, "He doesn't have." Okay? Not "they no like chocolate" but, "They don't like chocolate." So make sure you learn how to make negative sentences. "He doesn't"; "I don't"; "we don't"; "they don't"; not "he no", "she no", "I no". All right? Now, let's move on to No. 5. Finally, here we have a word choice error. And this is because maybe speakers translate from their own language, and many languages, you can use the verbs "meet" or "know" to talk about going to places and getting to know cities and towns, for example. So, "I want to meet the city" or, "Yesterday, I knew downtown." Now, in English, we don't really use the verbs "know" and "meet" to talk about getting to know a place. You can use the verbs "explore" or "get to know" or "visit". So you can say, you know, "I want to explore the city." I want to go around the city." "Yesterday, I knew downtown" -- "Yesterday, I traveled around downtown." And you can also use terms like "get to know" a place. You can visit a place. You can explore a place. Okay? But you can't meet a park. You can meet a person, but you can't meet a place. Now, let's review all five of these mistakes one more time. All right. So to review, No. 1, "I am a student." If you want to talk about your status in life. Are you a student? An engineer? Are you a teacher? Etc. you need to use an article to talk about jobs, professions, talk about your station in life. No. 2, "I agree, not "I am agree"." Do you agree?" Not "are you agree?" No. 3, "I went downtown." "I saw my cousin." So remember, memorize those past tense verbs. Not "I was go" or "I am go". "I went"; "I saw"; "I did". All right?

Heft's history teacher gave his class an open-ended assignment: make a project illustrating your interest in American history. So Heft redesigned the 48-star American flag to include two additional stars for Hawaii and Alaska. Though his teacher was not impressed, President Dwight D. Eisenhower ultimately took an interest … The rest, as they say, is history.

Support Veritasium on Patreon http://bit.ly/VePatreon Check out Audible: http://bit.ly/AudibleVe Want to watch the whole hour of silence? http://youtu.be/jr1UMFC9DV0 Many stories have circulated claiming the longest anyone has stayed in an ultra-quiet anechoic chamber is 45 minutes, the reason being any longer would drive you insane. To me this sounded like unsubstantiated rubbish, like the claim the Great Wall is the only manmade structure visible from space. So I put my own psyche on the line, subjecting myself to over an hour of the most intense quiet on Earth. No, this was not THE quietest room on Earth (-9dB) but it is one of the quietest, and the truth is once you put a person inside, they are by far the loudest thing in there so the sound rating of the room is irrelevant. I was not surprised to find that I could stay in there for as long as I liked and feel perfectly fine. What was surprising is that my heartbeat was audible. You can hear it on the sound recording. Now I wasn't consciously aware of the sound of my heart while in the room, but I was more aware of the feeling of it beating.

How do you measure big forces accurately? By calibrating your force transducer on the world's biggest weight - 1,000,000 pounds of force. This machine ensures planes don't break apart, jets provide required thrust, and rockets make it to their destination. Thanks to the people at NIST for showing me around: Rick Seifarth and Ben Stein.

Special thanks to Patreon Supporters: Tony Fadell, Donal Botkin, Jeff Straathof, Zach Mueller, Ron Neal, Nathan Hansen Support Veritasium on Patreon: http://ve42.co/patreon Before visiting NIST in Washington DC I had no idea machines like this existed. Surely there's an accurate way to measure forces without creating such a huge known force?! Nope. This appears to be the best way, with a stack of 20 x 50,000 lb masses creating a maximum force of 4.45 MN or 1,000,000 pounds of force. I also wouldn't have thought about all the corrections that need applying - for example buoyancy subtracts about 125 pounds from the weight of the stack. Plus the local gravitational field strength must be taken into account. And, the gravitational field varies below grade. All of this must be taken into account in order to limit uncertainty to just five parts per million (.0005%) Music from The Epidemic Sound http://epidemicsound.com "Serene Story 2"

Subscribe to Veritasium - it's free! http://bit.ly/YSWpWm As a Canadian-Australian, I have always wondered why it is that Australia has so many venomous animals that can kill you while Canada has virtually none. But it's not just Australia - it seems like all beautiful, warm places are cursed with venomous native species. So I set out to find the truth: why have all these venomous species evolved in the world's best holiday destinations? I asked chemists, visited the zoo, interviewed entomologists and snake experts. The answer I found was complicated: 1. The majority of venomous species are ectotherms, cold-blooded creatures whose internal temperatures are governed by their surroundings. 2. This means they have limited periods of activity - mainly while it's warm out, and can only exert short bursts of energy, so they are generally "sit and wait" predators. This may explain why they, more than mammals or birds, evolved venom. 3. It also explains why there are more of these species in warm climates. There are more of all species in warm climates, but this trend is especially pronounced for ectotherms. 4. So there are a greater number of venomous species in warm places, simply because there are more species in warm places. Cold climates still have venomous creatures, like the rattlesnakes of Canada and European vipers. 5. But history also has a role to play. In Australia, there were no snakes until 20 million years ago when a venomous sea snake from Asia encountered the land, sending venomous species to all corners of the continent. Later non-venomous arrivals have done well in the tropics but not as well in Australia's colder climates, so venomous types still dominate there. Hawaii has no venomous land snakes and nor does Jamaica. 6. The recent ice age also would have driven ectotherms from the northern parts of the Northern Hemisphere. This is why there are no snakes in Ireland, for example.

E. Knowles Middleton Absolute Zero and the Conquest of Cold by Tom Shachtman The Science of Measurement, A Historical Survey by Herbert Arthur Klein Lehrbuch der Chemie by Jöns Jakob Berzelius Script: As an Australian-Canadian the Fahrenheit temperature scale always seemsed a bit arbitrary. I mean why does water freeze at 32 degrees? And what exactly does zero represent? According to many sources the Fahrenheit scale was defined by setting zero degrees equal to the temperature of an ice, salt, and water mixture and 100 degrees being roughly equal to human body temperature. But that isn’t true. The real story is much more interesting, and scientific... August 14th 1701 was almost certainly the worst day in the life of fifteen year-old Daniel Gabriel Fahrenheit. On that day both of his parents died suddenly from mushroom poisoning. He was sent from Poland, where he lived, to Amsterdam to become an apprentice bookkeeper. But Fahrenheit couldn’t stand his apprenticeship and ran away so many times his employers put out a warrant for his arrest. Traveling from city to city around Europe, he became fascinated with scientific instruments and in particular thermometers. In 1708, possibly seeking help with the warrant, Fahrenheit met with the mayor of Copenhagen, who happened to be the famous astronomer Ole Romer. Romer is known for observing the eclipses of Jupiter’s moons and realizing that variations in the timing of those eclipses was caused by the time it took light to reach Earth. In other words, he found a way to accurately measure the finite speed of light. But more pertinent to this story, in 1702 Romer was housebound after breaking his leg. To pass the time he devised a new temperature scale with the freezing point of water at 7.5 degrees and body temperature at 22.5 degrees. This might seem odd until you consider that Romer wanted the boiling point of water to be 60 degrees (as an astronomer, he had experience dividing things by 60). If you take this scale, divide it in half, in half again, and in half once more, you find the freezing point of water 1/8th up the scale, and human body temperature 3/8th up the scale. So at their meeting in 1708, Fahrenheit learned of Romer’s temperature scale and adopted it as his own, adjusting it slightly because he found it “inconvenient and inelegant on account of the fractional numbers”. So he scaled them up to 8 and 24. That is the original Fahrenheit scale. He produced thermometers for some time using this scale. But then, at some later time Fahrenheit multiplied all numbers on his scale by four, setting freezing point to the now familiar 32 and body temperature to 96. It’s unclear exactly why he did this. He may just have wanted finer precision in his measurements but I think there was a better reason. You see, Fahrenheit was an excellent instrument maker. His thermometers agreed with each other precisely, at a time when that was unheard of. He pioneered the use of mercury as a measuring liquid, which has the benefit of a much higher boiling point than the alcohol used in most other thermometers at the time. For these accomplishments, he was inducted into the British Royal Society. And we know he read the works of Newton, Boyle, and Hooke, in which he would have come across the idea that a one degree increase in temperature should correspond to a specific fractional increase in the volume of the measuring liquid. And today a one degree Fahrenheit increase in temperature increases the volume of mercury by exactly one part in 10,000. Is this just a coincidence? We’ll probably never know for sure because as an instrument maker Fahrenheit was secretive about his methods. But I think the data strongly suggests this was the case. So what exactly did zero represent on the scales of Fahrenheit and Romer? By many accounts it’s the temperature of a salt, ice and water mixture. But there are different descriptions of these mixtures and none of them actually produces the temperature they’re supposed to. More likely I think they picked the coldest temperature in winter, set that as zero and later used ice and brine to calibrate new thermometers. Now his scale is only used regularly in the Cayman Islands, Bahamas, Belize, oh and the United States of America.

The world's roundest object helps solve the longest running problem in measurement -- how to define the kilogram. Support Veritasium on Patreon: http://bit.ly/VePatreon A kilogram isn't what it used to be. Literally. The original name for it was the 'grave', proposed in 1793 but it fell victim to the French Revolution like its creator, Lavoisier. So begins the tale of the most unusual SI unit. The kilogram is the only base unit with a prefix in its name, and the only one still defined by a physical artifact, the international prototype kilogram or IPK. But the problem with this definition has long been apparent. The IPK doesn't seem to maintain its mass compared to 40 similar cylinders minted at the same time. The goal is therefore to eliminate the kilogram's dependence on a physical object. Two main approaches are being considered to achieve this end: the Avogadro Project and the Watt Balance. The Avogadro project aims to redefine Avogadro's constant (currently defined by the kilogram -- the number of atoms in 12 g of carbon-12) and reverse the relationship so that the kilogram is precisely specified by Avogadro's constant. This method required creating the most perfect sphere on Earth. It is made out of a single crystal of silicon 28 atoms. By carefully measuring the diameter, the volume can be precisely specified. Since the atom spacing of silicon is well known, the number of atoms in a sphere can be accurately calculated. This allows for a very precise determination of Avogadro's constant. Special thanks to Katie Green, Dr. David Farrant, the CSIRO, and the National Measurment Institute for their help. Thanks also to Nessy Hill for filming and reviewing earlier drafts of this video. There is debate as to whether this is truly the roundest object ever created. The Gravity Probe-B rotors are also spherical with very low tolerances such that they may in fact be rounder.

Alleles in the ABO System i = base (plain donut) IA = encodes A antigens IB = encodes B antigens Allele Combinations ii IAIA or IAi IBIB or IBi IAIB Antigens and Antibodies The antigens you have on your blood cells are recognized by your immune system as SELF antigens If foreign antigens are discovered in your body, antibodies (or immunoglobulins) will be made by B cells of the immune system Antibody Structure Antigen + Antibody = agglutination reaction Agglutination = the clumping of particles Latin: agglutinare meaning 'to glue' Mixing of all blood groups and the result KEY: CANNOT transfuse if foreign antigens are introduced!!! The Rh Antigen Inherited in Mendelian fashion! Medical issue: Rh- mother and Rh+ fetus Good News... Rho(D) Globulin Treatment ("RhoGAM")

The Science of Happiness The first MOOC to teach positive psychology. Learn science-based principles and practices for a happy, meaningful life. Register for The Science of Happiness from UC Berkeley at https://www.edx.org/courses. About this Course We all want to be happy, and there are countless ideas about what happiness is and how we can get some. But not many of those ideas are based on science. That's where this course comes in. "The Science of Happiness" is the first MOOC to teach the ground-breaking science of positive psychology, which explores the roots of a happy and meaningful life. Students will engage with some of the most provocative and practical lessons from this science, discovering how cutting-edge research can be applied to their own lives. Created by UC Berkeley's Greater Good Science Center, the course will zero in on a fundamental finding from positive psychology: that happiness is inextricably linked to having strong social connections and contributing to something bigger than yourself—the greater good. Students will learn about the cross-disciplinary research supporting this view, spanning the fields of psychology, neuroscience, evolutionary biology, and beyond. What's more, "The Science of Happiness" will offer students practical strategies for nurturing their own happiness. Research suggests that up to 40 percent of happiness depends on our habits and activities. So each week, students will learn a new research-tested practice that fosters social and emotional well-being—and the course will help them track their progress along the way. The course's co-instructors, Dacher Keltner and Emiliana Simon-Thomas, are not only leading authorities on positive psychology but also gifted teachers skilled at making science feel fun and personal. They'll be joined by world-renowned experts discussing themes like empathy, mindfulness, and gratitude—experts including Rick Hanson, Barbara Fredrickson, Paul Ekman, Sonja Lyubomirsky, and Jon Kabat-Zinn. Health professionals who register can earn continuing education units for their participation.
