1. ## The Flash

So, I was watching The Flash awhile ago and they were dealing with particle accelerators. As you know, Flash was created by a particle accelerator explosion that caused him to transform into a man with super speed. I know that doesn't actually but what is in a particle accelerator? What is a particle accelerator? A particle accelerator is a machine that uses electromagnetic fields to shoot charged particles to almost the speed of light, while containing them in beams. Particle accelerators have made big discovers, especially in medicine. They have been used for finding x-rays as well as the di
2. ## String Theory

Going back to theory based physics, we now have to look into what String Theory is now. So, to start off with a general idea of what it is, String Theory is the idea of one-dimensional objects called strings are able to move through space and time and interact with each other. Meaning, the idea of String Theory is the idea of multilevel universes living amongst each other. String Theory can also get into various subject (to solve problems) such as black hole physics, early universe cosmology, nuclear physics, and condensed matter physics. A big problem with the theory is that the full theory d
3. ## Steph Curry #2

Continuing from last post, we covered the footing, jump, and angle of the shot and how all that ties into a perfect shot. But that's not all that goes into a perfect shot. Oh and I forgot to mention about the angle, according to Professor John Fontanella, the ideal angles for a shot by height are here: 5’4"- 52.2 degree angle, 5’8″- 51.5 degree angle, 6’0″- 50.8 degree angle, 6’4″- 50.1 degree angle, 6’8″- 49.4 degree angle, 7’0″- 48.7 degree angle. Ok, so now we'll go into the basketball itself, as well as the spin. So, unlike the seams on a baseball or the ridges on a golf ball, basketballs
4. ## What Does Steph Think About?

Steph Curry moves to the right, plants his feet, jumps, shoots, and it's good! You here that all the time while watching a basketball game, especially while watching Steph Curry. But do you think the players know all the physics into making that perfect shot? Starting off before the shot, the footing, moving to the right or left and planting a foot to make a jump shot is how a player uses the physical forces. As a player moves to one side and plants his feet, the body coils. Springing off the floor to shoot not only is to go over the defender, but also, the upward motion of the shooter’s body
5. ## Speak! -er

Speak! Speak! I'm not talking to a dog, I'm talking to my speaker. Why won't it work? Maybe if I learn the physics of it, I could probably fix it. So, inside a speaker, an electromagnet is placed in front of a regular magnet. The regular magnet is fixed hard into position where the electromagnet is moveable. As electricity passes through the coil of the electromagnet, the direction of its magnetic field is rapidly changed. Meaning, that it is then attracted and repelled from the regular magnet, vibrating back and forth, creating a frequency. The frequency of the vibrations causes the pitch of
6. ## Are Air Bags Harmful or Useful?

You rely on an airbag to save your life in a big car crash. But should you trust your airbag to save you life? Does it always help you or does it do more damage? Airbags are controlled by the laws of motion and are activated and fired through a carefully controlled explosion. They are triggered by high velocity and open up at more than 200 mph. According to the NHTSA, these airbags have been responsible for 296 deaths, including 191 children, 92 drivers, an adult passengers. Problems started with early airbags. During crashes, they were inflating with such force that they killed or seriously
7. ## Car Crash

Bang! You've been in a huge car accident, totaling both cars. But, that's weird. You have no injuries. Why's that? Then, you look at the deflated white sack coming out of the steering wheel and then you're thankful. But, how did the little bag work to save your life? An airbag provides a force over time. This is known as impulse. The more time the force has to act on the passenger to slow them down, the less damage caused to the passenger. About 15 to 20 milliseconds after the collision occurs the crash sensors decide whether or not the crash is serious enough to inflate the airbag. If the cr
8. ## Superman Scenario 2

Last blog post, we concluded that Sheldon was right; Superman could not catch Lois Lane because he would not be able to get fast enough. For this post, we will assume he is able to get up to speed without reversing time. But, there is still a problem with the scenario, making Sheldon right again (spoiler again). Using the same distance and same time interval (30,000 miles in 3 seconds) he would then need to have an acceleration equal to 1.787 x 10^10 m/s^2, using the equation v = v0 + at. Next, if we assume that Superman has a relatively low mass, about 7 kilograms, that would still mean he w
9. ## Is Sheldon Right?

The story of Superman; Superman, hundred of thousands of miles away Lois Lane is falling from a 100-foot building taking 3 seconds to hit the ground(an example). Sheldon says there's no way for Superman to catch her without Lois getting killed. Leonard says the opposite? Who is right? Just to be an arse, I'm going to give it away. If you watch the show, you would know that Sheldon is always right, and in this case, he is right. So, in the scenario above, lets say Superman would have to travel 30,000 miles in a second to catch her. Therefore, he would have to travel about 5*10^10 m/s to catch
10. ## 3D Glasses

So how do 3D glasses work? Well basically, your eyes have to see slightly different images. In the real world, since your eyes are spaced apart, each eye gets a different view, therefore the brain puts the two pictures together to make a 3D image. Binocular vision; since our eyes are 2 inches apart, there are two different views. Have you ever looked at a 3D movie without glasses and see fuzziness? Well that's because they took original picture and shifted it like what our brain does. But the shifted image is only made of red and blue. So what the glasses do is the color filters separate the t
11. ## How Long Can Earth Live Without the Sun?

Looking at the title of this blog, how long can we live without the Sun? And what would happen if there was no sun? In about a week, the global temperature would drop to below 0. Some microorganisms would live, but most life on Earth would die. Plants would die off immediately, but large trees would stay awhile. The top of the oceans would freeze but below would stay insulated and not freezing for many years to come. So, theoretically, we could live in submarines in the lowest part of the oceans. But we could also make a nuclear or geothermal habitat to live on. Looking at if the Sun were to j
12. ## Worm/ Dumb holes

So what is a worm hole? It's a black hole. But with a twist. Literally. A spinning black hole is called a worm hole, which is believed to actually travel across space. But not going against the laws of physics, but by using the dimensions of the universe. So if you wanted to get across the universe, theoretically, a worm hole would bend the universe making where you are and your destination right next to each other, so you could get there instantaneously. Now going to a dumb hole, something that has been created on Earth, rather than trapping light, a dumb hole traps sound. So scientist can cr
13. ## Black holes 2

So going back to the idea of watching someone fall into a black hole, looking at all the movies, they do it wrong. In the movies, as you go into a black hole, they show your body getting ducked quickly into the hole, and sometimes they show your body stretching into it. That's not true. Actually as you approach the hole, you go slower and slower until you reach the Event Horizon, when you cross in a black hole, you can't return. Once you reach that point, your body freezes and the light coming off you turn red and then you disappear. Going back to the idea of forming a black hole, when a star
14. ## Black holes

So I was doing some research and I found a little knowledge about black holes. So basically everything in the world has something known as a Schwarzschild radius, if you we're to collapse anything into a tiny, tiny amount of space, it's density would be so large that it's gravitational pull would be so large that not even light can escape. Therefore, a black hole. If you compressed the entire Earth into the size of a peanut, it would create a black hole. So let's say that your friend was going to fall into one and you were watching. What would it look like? So as he approaches the black hole,
15. ## Denver vs. Patriots

So while watching the end of the game, the Patriots had a chance to save the game by kicking an onside kick about 20 yards and recovering it. But in order to do that, it requires little amount of force so it goes just 10 yards, close enough so the Patriots can recover. So today we're going to find the force but instead of a football we'll use just a ball. So let's say the ball is kicked with an initial speed of 10 meters per second. And time goes fast here so they need to get it by in 2 seconds. Will it reach 10 yards in 2 seconds ? Well first we have to see what we have; Vi = 10 m/s, Vf =0 m/
