If the Earth were the size of a basketball and the moon a tennis ball, how far apart would they be? Diagrams that are not to scale make us think that they re closer than they really are.

A song about Gravity set to the tune of John Mayer s Gravity. Gravity is working with me And Gravity, keeps me on the ground All mass attracts all other mass a force proportional to mass one and two and inversely to the distance between them squared Oh, gravity is working with me and gravity, makes apples fall to ground Oh twice the mass has twice the pull but the force on each is still equal It keeps the moon and the satellites going round Oh twice the mass has twice the pull but the force on each is still equal It keeps the moon and the satellites going round Oh gravity, the force that makes weight on me Woah, gravity, now general relativity (how can that be?) The force between us all is The force between us all is The force between us all is Gravity between us all is Gravity between us all is Gravity between gravity between us all is

If you spin a raw egg and then stop it, it will start spinning again without you having to touch it. A boiled egg, on the other hand, stops and stays stopped. Why is this? Well a raw egg contains a yolk that moves inside the egg independently of the shell. If you stop the shell, the yolk inside continues to move due to its inertia and it therefore gets the egg spinning again.

There is a common perception that weight and mass are basically the same thing. This video aims to tease out the difference between mass and weight by asking people what makes a car difficult to push. The standard answer is that it is difficult to push because it s heavy. But heaviness is a measure of weight, the gravitational pull of the Earth attracting the car to Earth s center. When the car is pushed on a flat road, the force of gravity does not oppose the motion. Instead the resistance felt is an indication of the car s mass which determines its inertia. Inertia is the property of matter that means it tends to resist acceleration - the greater the mass, the less the acceleration for a given amount of force.

We used an acoustic trigger to take a well timed photo of a ball being hit. We added a 1 millisecond delay to the photo so the ball is shown just jumping off the bat. Note the slight "squish" of the ball. I made the acoustic trigger by using a piezo element to bias a transistor which in turn switched a silicon controlled rectifier. A special thanks to Daniel and his dad for being a good sport and swinging in the dark. Pennywhistle Productions

Well an atom s made of protons, neutrons, and electrons the first two in the nucleus, the third around it it s mostly empty space, but it feels solid in any case The elements are all the different types of atoms they differ by the number of protons in the middle. Hydrogen has only one, but Uranium has a ton It s just chemistry that you and me are made of these atoms Well atoms bond together to form molecules Most of what s surrounding me and you Water, sugar, things yet undreamed of of of of Look around you, see the combinations in a eucalypt tree Mendeleev s periodicity gives us sand and water and the air above ove ove ove ove It s just chemistry that you and me are made of these atoms: Hydrogen, Oxygen, Carbon, Nitrogen, make up the world s life forms Do do do you, do do do do but do you wonder how matter forms something strange when there s a chemical change? Where did these atoms come from? They were fused in stars Light elements combine releasing light from afar Fusion in the sun, creates Helium I guess what I be saying is you gotta use your reason To open up your mind and see the cause of the seasons -How do we know what s true? The scientific method shows you It s just chemistry that you and me are made of these atoms Atoms bond together to form molecules Most of what s surrounding me and you Water, sugar, sand and you ll find things undreamed of So Argon, Neon, Xenon There s no need to overstate Cause we are of course This, of this, of this, we re made: atoms

Scientists have to work with some very large and some very small numbers. To represent these numbers more easily, they use scientific notation. Scientific notation relies on powers of 10. This video gives examples of how to represent a large and small number and explains powers of ten.

JJ Thomson proposed the first model of the atom with subatomic structure. He had performed a series of experiments and was credited with the discovery of the first sub-atomic particle, the electron. He therefore proposed a new model of the atom called the plum pudding model. In this model, the plums represent negatively charged electrons which can be plucked out of the atom, leaving behind some positively charged pudding. In this film, cherry tart is used as a delicious substitute for plum pudding.

Angular momentum = Omega x Inertia where Inertia = mR^2 Omega= Angular Velocity

Aliasing occurs when your measurement frequency is not fast enough to accurately capture the measured event. In general, you want your measurement device to be one order of magnitude faster than the event being measured. From Wikipedia: accessed January 9th 2011 "In signal processing and related disciplines, aliasing refers to an effect that causes different signals to become indistinguishable (or aliases of one another) when sampled. It also refers to the distortion or artifact that results when the signal reconstructed from samples is different from the original continuous signal."

This is the first Veritasium science video. It addresses one of the most fundamental concepts in science: the idea that all things are made of atoms, tiny particles that are in perpetual motion. They attract each other when a little distance apart and repel when squeezed together.

Click link to Ssare with friends via Facebook! --- http://on.fb.me/CHICKENCAM2 -- Someone suggested I put a camera on my head and filmed some comparison footage. Tweet this video: http://bit.ly/hp7GI3 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~ GET SMARTER SECTION: I had already filmed this video, and my daughter is cuter. Isn t she a good sport? We had another rooster in a cage on the floor behind her, hence her 2 chicken comment. My favorite part is when she lets me put the chicken on her head and acts as if everything is perfectly normal. I m trying to teach her the concept of "performing a test". She s getting is pretty well. We re starting to test matchbox cars to see which is the fastest and things like that. if you are interested in helping us via a microscholarship (very micro) contact me for more info. Also, after seeing my "design" another user, Jeremiahjw was inspired to create his own chicken steadicam.

Click to Facebook this! ------ http://on.fb.me/eMSaVR 1st North Alabama Christmas snow since 1963. I hope your Christmas was more fun than watching Rednecks in a snowstorm! We act like crazies when it snows down here. Tweet this: http://bit.ly/guF3my I m guessing the first significant significant snow in 10 years or so on Christmas is due to global warming. Merry late Christmas! Pennywhistle Productions

I created a chicken powered steadicam then performed an experiment on the apparatus to try to backdrive the motion control algorithm. It seemed to work pretty well. More experiments to come.... Please subscribe!

http://twitter.com/#!/SmarterYoutube Click to share via Facebook!---- http://on.fb.me/CHICKENCAM ----- I waited a couple of years for someone to make this video, so I finally decided to do it myself. I shot the video about three months ago and just now edited it down. The micro camera website mentioned above has lots of examples of what this camera is an how to operate it. You d be pretty amazed how many uses there are for one. I hope you enjoy! If you enjoy my stuff, I would appreciate it if you subscribe! I ve also posted another video which investigates the "Backdriven reflex" in more depth. It can be viewed here: http://www.youtube.com/watch?v=JvPhBJpCeGg People are often worried about how tight the binder was on the chicken s head. You ll note I said "without hurting the chicken". I stretched the binder out so it had a very light clamping force. Also, this video inspired another user, Jeremiahjw to create his own chicken powered steadicam.
