The following extraordinary experiment from Caltech highlights the 'classical' behaviour of light(photons) traveling through medium. It vindicates the notion that photons(at least from our limiting human perspective) do behave the same way as other quanta(much like ordinary 'matter' - chairs...

First I am not sure if this is the correct place to post this thread, but the thread will be about optics, quantum physics and special relativity, so it is a mixed subject. Please watch this video first: This technology allows capturing videos at mind blowing 1 trillion fps, which allows us...

Why 1 slug is equal to 15.59 kg ? In FPS system we use slug as a unit of mass and pounds as a unit of force but sometimes we also use pounds as mass .I know that pound-force and pound-mass are almost equal at Earth's surface . But both these quantities have differelnt dimensions then how can we...

So if i take a picture (for example) 30 fps camera. So my question is that: is the time in the picture 1 s \ 30 fps or is it just 0? (May be very stupid question)

from a bit of googling, i realize it's because the frame rate of the camera and the projector are different. however, i have tried recording videos with cameras of 60fps, 30fps and 15fps, and the projector is likely 60 fps. That's why I'm curious about this - which frame rate is faster (the...

Hello! I have a PAL TV, and that means it is best for footage of 25fps and 50fps The TV's refresh rate is 200Hz Well, my questions are: What happens if I play an NTSC file on the TV? (≈30fps), since it doesn't go well with 200Hz much (isn't a multiple)... I thought about how would the TV...

I found this clip pretty educational and interesting. It shows the structural failure of a so-called Prince Rupert's Drop filmed at 130 000 fps (I had not heard about that concept before). Seeing the structure break down from the tail to the head at high speed is pretty amazing, I think :smile...

I'm probably getting 10-15 fps in Far Cry 3. The game is extremely jittery and barely playable. I even tried turning down the graphics settings to the lowest possible and I still have the problem. I have a $3,000 enthusiast gaming PC with multiple graphics cards.

This is nothing short of amazing. MIT figured out a way back in February to view how light 'moves' on, about and through objects. Here is a link: http://www.youtube.com/watch?v=snSIRJ2brEk&feature=related They apparently use multiple staggered high speed cameras to capture the images and...

Homework Statement So. I'm a muzzleloader hunter. If my rifle has a sight height of .85 inches. and groups at 25yards are 1.5 inches above 0 and groups at 50 yards are 2.5 inches above 0. The bullet I'm using has a ballistic coefficient of .205. The bullet weight is 240 grains. Is it possible...

I remember the command for the first Crysis being r_displayinfo=1 But what do I type into the console to display my framerate in Crysis 2? I bought the full game from best buy yesterday. I can run the game very smoothly on the "extreme" preset on 1920x1080 with no noticeable slowdowns. I...

I'm trying to look how the formula made on this http://www.gamedev.net/reference/programming/features/quatcam/page2.asp" . I want to know how this formula was derived. I tried to look on Quaternions and Rotation Sequences book but they use sin/cos which is so different on this. N.w = a.w*b.w...

Hello everyone. I got a speeding ticket for doing 53mph in a 35mph zone. (he origionally said 55mph so both calculations would be great) I was at a dead stop he said I punched it and got to 55mph before he pulled me over. My truck is a 2007 tundra that goes 0-60 in 6.7 seconds and the quarter...

I posted a few days ago . . . I think the point of my question has been missed. It was generally about ballistics. I elected not to go into any specifics because this is a physics forum not the FiringLine forum. So, I will specify and simplify . . . Here is my question. If a sphere is...

Does anyone have a good explanation of what fields per second our eyes see, and why it is at that? By why I don't mean evolutionary features, I mean optically, such as beyond a certain fps the our biological singular value decomposition does not not amount to much, something physics or mathy.

Some television standards show images at 50/60 fps. Action games are meant to be played at 70-80 fps. But, if our eyes maintain the image only for like 1/6th of a second.. why is that we can detect flutter even at 24 fps in some cases [sometimes flutter is visible even at 30 fps or something]...

Anyone play them? What's your favorite? Personally, I'd have to say morrowind/oblivion are my favorite role playing games. Fav of all time would have to be star craft and quake world team fortress

This is probably one of the best FPS out there. Developed by the US Army, highly challenging, requires some strategy, teamwork and it's FREE! And now back to my so-called life...

Hi! I'm trying to implement a FPS-camera. I need to calculate a new vector from another one, rotated a. This is of cource in 2D. Is this correct: x' = x * ||v|| sin a / y y' = - y ||v|| cos a / x
