  3. I remember watching a Curious George episode as a kid that explained hot air balloons and it blew my mind
  4. This is an example of how magnets can be used for levitation, or hovering if you will. All this is, is simply the force of the magnet overcoming the force of gravity of the magnet and the liquid. In this way, a "hover board" would be nothing other than a force keeping something off the ground, which is just what a normal force is when you have an object sitting on the floor. However, using magnets for levitation is cool because you cannot see the force acting on the object, and the force can also be transferred through things, putting your hand between something being levitated by a magnet wou
  5. Pole vaulting is a very good example of the transfer of momentum. You are transferring energy from running down the runway into bend in the pole, and then that pole rotates after you jump, making the pole push you vertically. As a pole vaulter myself, I can say it is not all that complicated, it does not require you to be a physics student to get over the bar. However, it is super fun! It must be flying in the air and feeling the push of the pole behind you as you kick your legs up, hoping to get over that height you set for yourself. Common things people will say about pole va
  6. Personally I prefer building wall with working outlets and light switches over building a circuit in a lab, we do this in my Electric and Alternative Energy class. To me it just makes more sense, and I guess my time in physics is what gives me a good sense of how things like the electrical guts of a wall actually work. It seems like knowing how electrons flow through a system and through a switch is the basics for any circuit, functional or theoretical. However, I like that putting together a wall in this trades class that I take is actually quite challenging to understand still. Every basic w
  7. This is a video of a levitating frog. Apparently a 10 Tesla magnetic coil is being used to lift him. This is possible because pretty much all organisms have small amounts of ferromagnetic materials inside of them. And no this does not hurt the frog because the force is spread out over the entire body, but he is probably freaking out a little bit inside.
  8. Some magnets are more, uh, magnetic than others? Yes some magnets have a stronger magnetic force than others. Iron, nickel and cobalt atoms have more electrons orbiting in one direction than the other. This means they produce smaller currents like electromagnets. However, ferromagnetic metals like iron, nickel and cobalt like to line up into larger areas. These areas will line up, north to south like any other magnet if you put them in a strong magnetic field. You can even line up these areas yourself, maybe you've done this before, you take an actual magnet and rub it one way across a f
  9. Today at my locker, I took a stand against lockers everywhere. Every morning coming into school I visit my locker first thing to put away my jacket. I have been needing to wear a jacket for longer this year because of the ceaseless cold we've been having here in New York. To get to the point, I would come in from the cold wearing my jacket and go to my locker to put it away for the day. Like rubbing your socks on a carpet to induce a charge on yourself, the act of taking off my fleece jacket rubs it on my shirt, inducing the charge. This charge is then discharged when I touch my locker to hang
  10. I've been watching this gif for like 5 straight minutes
  11. Concise and profound, homerun.
  12. 1 Gauss = Mx/cm2 = 10-4T = a guy = /gous/ noun, a unit of magnetic induction 1 Tesla = measurements for magnetic fields = 104G = the SI unit of magnetic flux density = another guy 1 Newton = who knows? Wow look, these units are all named after some cool science guys, this is concurrent with many other units; Ampere, Kelvin, Pascal, Coulomb, Watt, Volt(a), Ohm, Farad(ay), Weber, Joule, and of course the Becquerel named after none other than Antoine Henri Becquerel. Seems like you gotta be a pretty smart science guy to have a unit named after you, wonder when we'll get the Ny
  13. This sounds very similar to a philosophical idea known as Occam's razor, you can look into it a bit, I don't trust myself to know enough about it to explain it here in the depths of the comment section.
  14. A common use of a brush motor is in a fan, for example the type that is used to keep my laptop from overheating. But what exactly is that preventing, and what does overheating do to a system such as a laptop? The fan helps to keep internal units cooled down, heat is created when there is resistance in the different hardware inside the computer. With all the units preforming very close to each other, a lot of heat can be generated. This is why keeping any appliance that generates a lot of resistance should be turned off when not in use, they are just draining unnecessary power and can crea
  15. What exactly happens when electricity flows through a person, how does it effect their body and how can these effects be measured? People are conductive, electricity will flow through a person if able, and can do harm to a persons body, including burns and upsetting the heart. Small enough voltages might not conduct through your skin, the most susceptible place on your body is probably your tongue. In terms of Amps, 1 mA of current through your body would only cause tingling, but upwards of 75 mA could cause ventricular fibrillation, an unsteady heart rhythm that can lead to death.
  16. My Semester Review Pledge to physics: I really think math is fun, it's like a puzzle, seriously no sarcasm here, I really enjoy taking math tests. They are surreal in a way, and I don't even know what surreal means, they just are and that sounds cool. But time goes by so fast and I just feel like super cool when I know what's going on, like we're speaking some secret code or something that only our class knows how to speak. Now, I need to take that same fascination and put it into the physics setting. Something about physics is different than math, perhaps it's that it's not the sam
  17. I recently had my wisdom teeth removed, and it wasn't even the worst experience of my life, all thanks to the Novocain. My face was completely numb, couldn't feel a thing. It's not like I couldn't feel any forces though: I could tell that my cheek was being pulled to one side because my hole head felt the force of the pull, but I could not feel anything touching my cheek, an odd experience. And after the surgery I was touching my face a lot because touching your own face when it is numb is a very weird sensation, hard to describe. And this got me to realize that when something touches you, som

    Green is my favorite color, here's why: the frequency of green light is 526-606 THz(Terahertz) and it's wavelength is 495-570 nm In my opinion, green should replace yellow as a primary color, it is just so much better The colors displayed by your computer screen or TV are made of super tiny pixels made of 3 different colors, red GREEN and blue, hence RGB VS Seeing these colors very zoomed out(as your eye does) can make them seem like any other color on the spectrum from black to white But why green and not yellow, it would make sense for it to be yell

    I was at Wendy's today, getting a drink, from one of those fancy drink dispensers. It is amazing how there are so many flavors and types of drinks to choose from, a massive increase in choice from those old ones where you could choose from a variety of like ten drinks, now it's more like 100. The machines are very compact too, all the drinks are dispensed from the same exact place on the machine. The machine is coded itself to of course give you the drink of your desire, go on the menu and select your type of drink and flavor until you've gotten to a specific drink of your liking, then hit the
  20. The game of Hacky Sack is a good one. Full of skill and such. The "footbag" itself goes through a lot of getting smacked around, flying through the air in parabolic arcs like any other projectile. The players in the game have to pretty much predict where the hacky sack is going to be when they hit it. Of course no one is going to set up an equation to see where the sack is and where it is going to be, that is absurd. Rather in this fast paced game players get used to the force they hit the sack with and then from there are able to use their sense of sight to see where the ball is going. This i
  21. So decibels are the measure of the intensity of sound, does that relate to the amplitude of the sound waves, or maybe the frequency?
  22. I was going for a nice walk today, it was a bit cold, but it didn't bother me too much. And I didn't too much mind the somewhat cloudy sky, the sprinkled snow on the ground was a nice touch as well. At one point I came to a spot on the sidewalk where the ground beneath my feet was no longer cement, it was ice. BUT THIS, this was no fine smooth sheet of ice, this was a cracked earth beneath my feet. The first crackle that reached me made me believe that I had just found my way onto some broken glass bottle, but a quick somewhat concerned glance below proved the sound to be
  23. My good ol' guitar has been getting out of tune recently, I think it's time for a restring. The strings were not strung in the best possible way to begin with so they have slowly over time been slipping out of the tuners. Even if the guitar is re-tuned, the strings will continue to slip more and more, so they need to be taken off and replaced. I have however been putting this off for a while, while the guitar is still playable it sounds not the best. The first time I restrung my guitar, I was tuning it and a string broke, luckily it didn't hit me while flying off, because those things hurt. Th

    You may have heard before that potential energy can be described as the amount of damage something can do. Mr. Powlin gave us the example last year of something with a greater mass or speed will do more 'damage'. It should be also noted that the area which is affected by the force will determine the 'damage' and the duration of the impact. Also how the force is distributed into the object receiving the force. For example, a skier who weighs 150 lbs going 20 mph can lessen the damage of a fall by landing over a large surface area by spreading out, landing on his side rather than on an out
