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...

Homework Statement Watch the crash test video , and determine the following: 1. How fast is one of the crash test dummies thrown forward (the crash at :34 seconds) ? Pick either one, and be clear how you estimate this. 2. Assuming the speed you got from part (1), how high would a different...

From Google news, http://www.theregister.co.uk/2015/02/18/meteor_explodes_over_Earth's_beaver_in_hot_nasa_video/ Simple question, if you play the video in the link above the light from the meteor flairs up into a very large ball of light. Why don't we continue to see a relatively small point...

As the title says I am looking for some book to read and understand this world. I know many people say its impossible and that we can learn it by learning the math bluh bluh.. But i have passed 4 quantum courses and i know the math. I just can't get the touchable concepts ( i don't really know...

I didn't know where to post this, but, this video makes my eyes water.

Homework Statement The problem I have is not actually so much a physics problem but more of a logical problem. When we look at rulers and any kind of measuring tools, we start from zero. We count the number of intervals instead of the divisions. Suppose we have a video with 7 frames per...

Hi.. I take a high school physics Olympiad. Could you please tell me what the best physics video channel on YouTube or other sites ? I'm looking for videos that gives an overview to an advanced problem (It can be IPhO level) and guide to the solution step by step..

Wasn't sure where I should post this link: astronaut view of re-entry- http://spaceref.com/missions-and-programs/nasa/video-nasa-provides-an-astronauts-eye-view-of-orions-re-entry.html

I have the books and audios. But I have yet to find the videos. I am wondering whether they exist.

Hi. I wasn't sure where to post this, but wanted to share this amazing video. From the smallest to the biggest thing in the universe:

Kerbal Space Program has been successful, but I wonder if anyone has messed with a game called "Space Engineers". It's a sandbox space engineering game. http://store.steampowered.com/app/244850/ @collinsmark

Go to 1:24 of this video: He recalls some integral he wrote at a young age: " ... times the sixty-fourth power of ... what?" and looks confused. At 1:44 Neil Degrasse Tyson says, "By the way, the answer to your little calculation is i." Can someone explain the historical reference to me...

Hello everyone, So first I'll give an overview of the project that I am working on. We have a camera system that we wish to control on a Windows 8 tablet. The program on the tablet will need to display the video signal and also be able to issue commands to the camera (currently, just change the...

My take is: The magnets are conductive and complete an electric circuit composed of the battery and a section of the coil (toroid) thereby forming a solenoid. The battery-magnet assembly is in the center of the solenoid. The magnetic field of the solenoid is maximum at the center and decreases...

My local PBS station broadcasts a physics series on a sub-channel. They call it The Mechanical Universe locally. PBS recently broadcast The Lorentz Transformation . It appears that one may view these on line, as the Lorentz Transformation began to load after I allowed it to pop-up. There are...

in this video question no 5 actually it is first question of the video but it's number is 5,i didn't understand this question.first i thought The force acting on block A is its weight in vertically downward direction, with no friction with the wall and Condition for equillibrium: Sigma Fx= 0...

Hey guys, I am working on a video game which is based on electrostatics. You play a charged sphere and you can change its charge to interact with other charged objects, sticking to walls and ceilings and orbiting around other charges etc. I am curious what you think of the concept, and which...

I thought others might be interested in an old educational paper and fim demonstrating that you can't accelerate material objects past c. Bertozzi, Speed and kinetic energy of relativistic electrons, Am. J. Phys. 32 (1964) 551 The Ultimate Speed - An Exploration with High Energy Electrons -...

This (in my opinion) is the most beautiful, relaxing, and soothing song from any video game in history. Video game music has really come a long way. From the game Deus Ex Human Revolution.

I just saw this video and wanted to share it. It contains some pretty awesome plots of the motion of galaxies in our neighborhood. Here's a longer video made by the same person:

[SIZE="4"]"This is Your Brain on a Laser Beam" Around the middle of the video he starts talking about shooting consciousness on a laser beam into the heavens. What would be the point of that? I finished watching the video and I'm like "WTF is this guy talking about?"

Seriously excellent talk given Monday 23 June at the Princeton Strings 2014 conference by Paul Steinhardt: http://physics.princeton.edu/strings2014/videos/talk1h.mp4 You may have to pause it and wait for buffering. I found that after the video had played through I could drag the button back...

Could you please give me example of situations when changing the aperture ( that means the depth of field, and exposure, right? ) is necessary during shooting the same video clip?

I don't see why not but is there any reason that i could not use these modules http://www.ebay.com/itm/121370353437?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649 to make a wireless link between this camera and screen...

Can I use a 315MHz transmitter module to send a composite video signal to another reciever module?

trying to find a good esd or assembly craftsmanship video for employees in a small business, I've seen some in the past, one i saw had R Lee Ermey (from full metal jacket) in it, it was pretty convincing. obviously, a lot of people don't take esd seriously. i saw another one with a good...

Hi I play a video game (DDO to be specific). In this game I can chose one of 2 options the first (Keen Edge) increases my Critical hit rate by 10% permanently, the second option (Exploit Weakness) increases my critical hit rate by 10% each time I do not make a critical hit (e.g. Attack 1 crits...

My initial thought was that the plane wouldn't be able to take off. If the conveyor is moving in the opposite direction as the plane, at the same speed, then the plane wouldn't move relative to the ground (as if you're running on a treadmill, you're not actually changing position relative to the...

hi everyone,i know that the phase spectrum contains most of the structural information about the image.But i want to know more about importance of phase spectrum related to video signals. I have read that temporal variations of phase values are able to capture most of the dynamical...

I have a number of questions about the above video: What are they using to move the atoms? What are the wave-like lines around the shape/atoms? Why can't we see the atoms of the material that the video was filmed on (i.e. the background)? Side question - What do atoms have to do with data...

I can't do much about the crappy pronunciation, but if anything acts on your nerves, please tell. And in general, if you think something is wrong about the idea/approach/execution - fire away. Note: it is about video, not about the software. That is, I have nothing against comments about the...

I never upload video onto Youtube. 1) I can video tape ".MOV" with my Nikon SLR. Can I upload onto Youtube? 2) The file is very large, would that be a problem? If so, what can I do? 3) Any instruction how to upload to Youtube? Thanks

I want to be an electrical engineer or mining engineer when I grow up and I want to get a BS in both of those fields, but I was just wondering if I could get a job as a video game designer with a degree in electrical engineering.
