  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
  16. Ok, so this the best I can find, go to about 2:00 and watch that little bit (where he is working on the rocket). https://www.youtube.com/watch?v=E9A0Dev7DQw I thought this could be a fun one to use to talk about rockets! Ok, I guess I'm more talking about a question I got wrong on a recent test. So the question was why do objects in a rocket that is in orbit around Earth appear weightless? I've done some research and I'm ready to give it another try. As it turns out, for a rocket or space station in orbit around Earth, there is an acceleration downward. So technically, the space ship
  17. I cannot even begin to understand how this ever worked but somehow in this episode the Scorpion team ran a significant amount of electricity through one persons head and basically turned him super human. You are probably wondering where the physics comes into this: he pretty much bounced off and over a moving car to chase somebody down. I couldn't really find a video or an image but it is still free to watch on CBS.com (http://www.cbs.com/shows/scorpion/video/DE90E9B6-555F-4C3B-10AD-FE20D5CFE4A9/scorpion-forget-me-nots/). The scene I'm referring too happens at about 20:00 so you can skip
  18. I like this episode because it has a really cool example of projectile motion. (Read the next line BEFORE you play the video please or you might be a bit confused). Skip to around 1:15 in this video and watch (this is the only video I could find it in) and you'll see. The Doctor (or John Smith in this one, he has forgotten who he actually in this episode) manages to throw a cricket ball in the exact way that it hits a stack of poles that fall over and cause a brick to launch and hit a metal jug that stops the women from push her baby- inadvertently- under the falling piano. Yeah
  19. From this episode I get to talk about something pretty neat: solar flares. Yes, the plot of this episode revolves around a magical forest covering the Earth over night in order to save it from a massive solar flare. Confused yet? Solar flares are massive explosions on the surface of the Sun that release a significant amount of energy in multiple forms at once. A solar flare occurs when magnetic energy that has built up in the solar atmosphere is suddenly released. So, one of the most important types is the release of electro-magnetic energy. So while it looks like a huge spike of fire i
  20. There are just a few bad physics moments in this episode and so I thought it would be a good one to talk about. Ok, so this is the scene: As this girl (Happy) is climbing a glass building using nothing but gloves with suction cups on them (which is one of the things I'm not sure made sense) she starts slipping. Meanwhile the two guys on the ground (Toby and Sylvester) are having this conversation. Toby: Sylvester, think of something! Sylvester: Okay, okay! The force of gravity is 9.81 meters per second squared. If she swings hard to her left, then her right hand would completel
  21. So this is about 24 days too late but... So, I have question for you. I really hope not. I thought I could use the Christmas Special to talk about the physics of Santa's sleigh, since he was a main focus of the episode and my research yielded so interesting results. (If you still believe in Santa, skip to the very end or you will never be the same again) Santa has over 300 million Children to deliver presents to and approximately 31 hours- with different time zones taken in to account- to so. IF we use the census and assume an average number of kids per household, the numb
  22. (I'm not sure if she has been in a post yet so this is one of the Doctor's Companions and her name is Rose) Anyways, I'm working on a post about the Doctor who Christmas special but for now I'm going try another one about Scorpion! Ok so I'm not saying the physics are wrong (ok, maybe not COMPLETELY wrong) but lets just talk this out and you can decide for yourself. What really gets me is the connection between the two cords in the video, you can see it if you pause the video around 1:20. It is COMPLETELY vertical. There is no way the connection is strong to hold together agains
  23. Ok so I have to apologize, this blog is no longer only Doctor Who. I've realized that, unfortunately, I'm running out of ideas with Doctor Who so while I think up some more I've decided to branch out a bit and write about the brand new CBS drama Scorpion. It's about a team of geniuses and I've seen physics in practically every episode. That brings me to the episode I'm discussing. This one is the most recent and caught a little basic physics in it. So in this scene Walter- the main character and genius- is trying to figure out exactly where the car beneath must be positioned in order to all
  24. It seems fitting to close out my tenth and final blog for the first quarter by talking about the season finale of the 8th season of Doctor Who. In this episode the Twelve Doctor gets thrown out of moving plane and yet he still manages to call his T.A.R.D.I.S. in mid-fall. The Doctor would have been falling at a fairly quick rate, he would have been in free fall. Obviously, since he is able to catch up to the T.A.R.D.I.S., the T.A.R.D.I.S. is moving at a smaller speed. That would explain the fact that he can catch up the T.A.R.D.I.S. but it still does not mean he can get the key in the lock
  25. The title says it all. This episode is all about the Earth being stolen right out of orbit and out of the universe. Just imagine, if you were in a space above the planet, hearing "The Earth is gone!" and seeing nothing where your home planet used to be. But how could that happen? How is that even possible? In theory, it is possible but certainly not by human action (but then again it was not human action on the show). To occur naturally, an asteroid of large enough mass would need to pass by the Earth to pull just a small bit out of orbit and then the Earth would slowly move away fr
