  1. Justin- I had no idea that the tidal waves on Miller's planet were fixed waves, I did not even know that fixed waves could actually be possible in that sense (as stupid as that might sound). That is really cool (and kind of freaky). Jake- The idea of watching a live feed from Miller's planet is definitely something I would never have thought of, very cool! I think the idea of time dilation, as you described and applied it here, is pretty neat and a little bit scary. I can't imagine watching a live feed moving that slow! Nate- I actually was wondering about how Cooper could have gotten
  2. One of the physics concepts I picked up in Interstellar was the physics was the idea of a 5th dimension. I did some research and very quickly realized that I had opened the Pandora's box that is quantum physics. Simply put: I was lost. So I asked my physicist brother for some help and ended up getting a ten minute crash course in the dimensions. Here's what I got. To gain the perspective of another spacial dimension: When you hit a 2-dimensional drum set, which is in "flatland," you have to hit it from our third dimension, one in which the drum head would never perceive. Likewise, you can'
  3. It's everybody's favorite physics problem: the elevator! One does not learn mechanics without encountering the elevator problem (as far as I know). This is an interesting, sort of different take on it though. http://www.cbs.com/shows/scorpion/video/46616DDC-D143-4956-909B-9B31759797B6/scorpion-i-love-machines/ I'll be honest, the first I saw this I had no idea why Walter and Toby were tying their belts to the elevator bars. But it all makes sense about 5 seconds later when a rather...well....happy Happy stopped the elevator very suddenly. The belts looped around their arms and the elevat
  4. Drones! Yes, the flying machines with four propellers that are all too popular these days surfaced in an episode of Scorpion. I thought this might be a cool opportunity to examine the physics of how drones fly. We never get a good look at the drone in the episode, but I do know that its suppose to look like a bird (Sylvester calls it "Bird-Droney"). However, for the sake of this post, I'm going to the discuss the quad-rotor model of a drone (recreational drones). They usually look something like this: When it comes to the physics of how these things fly, we turn to our good friend Newto
  5. The throwing saga continues! This post is all about shot put (the one that looks like throwing a cannonball), my other event. In this a event, throwers compete to see who can launch a weighted metal ball (8 lbs for girls, 12 lbs for guys) the farthest distance. This fairly basic projectile motion, but a lot of people struggle with it. So, here goes: Actually, I lied. This is slightly more complex projectile motion since, as the diagram shows, the release point in a height (h) off of the ground (not on the ground) which changes out equations quite a bit. However, we know the equation of
  6. Hello again! As you might have guessed this post is not about a TV Show (though I could probably find a movie or show that involves what I'm going to talk about). I actually want to talk about the physics behind throwing a discus. The discus throw is one of the events I compete in with the school track team, so in honor of our first meet yesterday I decided to do a blog post on it. A "disc" or discus looks like this: The larger radii are for men while the smaller, lighter discus are for women. First things first: how does one throw a disc? The most important part of throwing a disc is r
  7. Let's talk about Ferraris. At the beginning of this episode Walter is given a Ferrari, which he immediately and excitedly points out can drive at speeds of at least 190 mph (some models can go as fast 214 mph). As one can imagine, this could turn out poorly. And turn out poorly it did. By the end of the episode and rage-filled Walter manages to send the vehicle- with him inside of course- over the side of a cliff. I will say, before I get into the physics of the crash, that the physics this time are actually pretty good (shockingly). (the link should take you to the point in the video yo
  8. So I've realized that with all the posts I've done on Doctor Who, I never actually looked at the theory behind how the T.A.R.D.I.S. can actually travel through time. There have actually been studies into how a time-travelling space might work in this universe and the findings have led physicists to believe it is theoretically possible for a T.A.R.D.I.S. to exist and to function as it does on the show in our universe. The research paper is called Traversable Achronal Retrograde Domains In Spacetime (see what they did there?) and it was written by a pair of physicists named Ben Tippet and Dav
  9. Thanks? I can split it into two posts if that would make it better.
  10. Yes, I'm adding another show! The other day I was watching a newer episode of the Big Bang Theory when I realized that there could be some good things to talk about in this show. After a bit a research, I was definitely right about that. So let's start here: So, Sheldon- a super smart astrophysicist- is trying to teach Penny- an average human with no knowledge of physics- about some basic physics concepts. One such concept is Newton's equations for gravity and gravitational force, or Newton's Law for Universal Gravitation. I should start this by saying that he his referring objects
  11. I really thought it would not get worse than a man standing on the wing of an accelerating plane, but I was wrong. In this episode, the team is trying to protect a witness from a gang that is trying to kill her and so obviously we have some high speed chases and what not. Well, according to the show, an RV travelling at 100 mph (~44.7 m/s) can make an almost 90-degree turn without crashing, tipping over, or slowing down at all. So, I'm going to use this blog post to prove them wrong. The first link here will explain the situation, the second is the RV making the turn. http://www.cbs.com/
  12. As I mentioned in the previous post, here is part II: the wildfire. Honestly, I just wanted to know if it is even physically possible for that many slow-moving people to out run a spreading wildfire, especially in high winds. Here's a short clip from the episode showing the spreading fire: http://www.cbs.com/shows/scorpion/video/45699904-3F02-8272-59C1-482673FE0BEF/scorpion-fire-is-getting-close/ So the first thing I noticed was that Sylvester (the man who was on his own dragging that other guy) was walking pretty much the entire time and he started at the epicenter of the fire. The other
  13. Ok so I know its been a while, but I'm back! This episode is about the Scorpion Team trying to save a group of lost hikers and getting caught in a wildfire in the process. http://www.cbs.com/shows/scorpion/video/60C5E5EA-F07C-9BE2-1635-482673FE41E0/scorpion-we-re-going-to-die/ I'll start here, with the falling helicopter. Helicopters fly through the use of propellers. As the propellers are rotated at increasing speeds , the air flowing over them generates lift. Because the the propellers rely on ability to create air flow to maintain this lift, high wind speeds create dangerous flying co
  14. Ok, so today is my midterm and I've been studying and looking over my notes and everything and I think I'm about ready. The test is going to be an actual AP Mechanics exam I guess, so I've done a few practice ones and such to get ready for it. I'm hoping that I can get at least a 4 on this thing. This going to be a short post for now but I plan to update this later after the exam so I can complain talk about it. I guess that's all I have to say for now. Wish me luck! OK, that's one exam down! I think the multiple choice was a little rough (and by rough I mean there some questions
  15. Hello again! This one I had to talk about because there is just so much wrong with the beginning that I don't even know where to start. Scratch that, yes I do. Let's start with the Doctor falling out of a spaceship exploding in orbit, that seems like a good place to me. I'm not sure if the Doctor has special lungs that don't need air (pretty sure that is not the case) but he survived for like 5 minutes hurtling towards Earth in space with no atmosphere. Than he reaches out into space and tries to swim to a nearby space suit. Both left the exploding space ship with the same velocity and
