I am reading the book "A History Of Optics" by Oliver Darrigol, and I came across this sentence (under the heading Visual Fire): Isn't this a low-quality argument? This can be directly disproved by the fact that humans inbabilty to see in dark, viz. if humans can see things from the "fire"...

I'm a biologist interested in physics. Biology is undergoing several revolutionary changes, but physics is interesting too! I am interested in the physical aspects of information processing in biological entities, things like: genetic control systems, information transmission through...

Hi, I'm having trouble figuring out how to copy the contents of a file over to another file, and removing an item of the content of the list I'm copying in the process. The idea is that I need to remove an item from a list by copying everything that is in file one over to file two that is not...

Hey, I'm in my first year of Electrical Engineering studies and finding a lot of common places in my studying and ways of approaching things that may be leaving me short. I really enjoy my circuit analysis class, I love learning the concepts, formulas and visualizing how they work in my head...

Hi all, I've got a high school special relativity physics test coming up in a week and thought I should post here instead of under homework/coursework as I don't really have any set questions that I'm asking. My problem is that I can explain the visual effects we learned but not with enough...

Homework Statement The Sun has an absolute visual magnitude of about 4.8 and a particular star has an absolute visual magnitude of –0.29. How many times more luminous is this star than the Sun, assuming these stars have similar spectral types and hence colours? a) 100 times b) 125 times c) 150...

Hi I downloaded visual studio 15 and as i saw some of its components need to be installed I tried to install them but it seems that its not compatible with my internet download (20kb/s download breaks after few minutes) So is there any way i can download them from microsoft and install them...

Hey all, So I just graduated community college with an associates degree. The program is essentially a chemical technician program. I'm currently employed at an agricultural company, but the job is not very mentally stimulating. I was thinking of pursuing a continuing education program...

Is it possible that 2 stars in a binary system to intersect their orbits like in this picture? ( the orbital plane is perpendicular to the line of sight)

Radio is usually used as RADAR blips but has anyone tried to make a visual DSLR type camera and producing images? I'm not talking about a waveform showing the frequency placement but a real image of objects the radio bounced off of? We have tons of radio stations as the 'light' source here in...

Hi I'm new here! I've always loved math and have been really good at figuring out how to solve word problems logically and figuring out math in general. When my teachers explain how to do problems i get confused/can't follow what they're saying but its usually fine because i can just figure it...

I'm under the impression that one sees clocks slow down when watching distant objects approaching strong sources of gravity, such black holes. And that objects in an elliptical orbit travel faster when they are near their attractor. I can't quite figure out how these two phenomenon work...

When I observe the UV light emitted, I can literally see the millions of photons appear and die within milliseconds, but nobody else around me can. When I observe IF light sources and transmitters in low light, it is the same characteristic, except there only appears to be to photon sources, and...

Supposed there is a tree on a perfectly flat plane. If an observer in front of that tree moves further and further away from the tree, the tree would look smaller and smaller. When the observer moves further and further away, would the lower part of the tree's trunk seem to disappear as if...

Hello folks, I was playing with a rectangular prism 4x4x3 (almost a cube) and I was giving him a rotating movement with the hand over the table so I could see a visual effect I have seen many times in my life and now I remembered to ask about it. So when I give to it an impulse and it start...

I have been doing a lot of reading about this and it seems really, really interesting. Correct me if I am wrong on any of this, but I'm going to attempt to summarize how traveling at the speed of light, or at least 99.998 percent the speed of light, would look in two different cases: in...

I am trying to compile several libraries of FORTRAN code and getting the error message as can be seen in the screen shot. As I do not have any experience with FORTRAN I am not sure what is wrong in the line highlighted line. Any help would be greatly appreciated! Thanks a lot! :-)

This is an original research project. Any ideas or guidance in the overlap of the two fields (i don't know much about the overlap).

Do you know any influential mathematicians that are visual thinkers? especially those who wrote books. For example mathematicians that think and write like Roger Penrose,Benoit Mendelbrot,Vladimir Arnold,Sir M.Atiyah who are very keen on using diagrams and drawings in their writings.

A visual proof of the following statement: If $\infty=\dfrac{1}{0}$, then $0=\dfrac{1}{\infty}$ . Proof: Assume $\infty=\dfrac{1}{0}$. Rotate each side of the equation counterclockwise $90^{\circ}$. We get 8 = −10. Subtract 8, getting 0 = −18. Then rotate both parts back...

Hi everyone, I just wanted to share this really cool game MIT Game Lab made, it's called A Slower Speed of Light: http://gamelab.mit.edu/games/a-slower-speed-of-light/ Sorry if this is already commonly known among people interested in SR (probably is- but maybe there's a few people who...

I've debugged and run my program without seeing any results from my "destinationVariable". What could be wrong? sub main() call myfunction() end sub sub myfunction() static myClock As Single myClock = timer if (timer - myClock) > 100 Then destinationVariable += 1 // This...

How Do I take projects created in Dev-Cpp and transfer it into Visual C++. I mean they are both C++ projects correct? I tried to open these projects in Visual C++, but they just don't want to open...erm I mean I can't open them. Help?

My group at work uses several pieces of legacy Fortran code which we've always compiled using Compaq Visual Fortran. Since CVF has not been supported for while now and is not (easily) compatible with Windows 7, I'd like to move to a more up-to-date compiler and IDE. I'm trying Simply Fortran...

If you were in a ship, traveling very close to the speed of light, what would it look like? Would the universe look like a bright dot out in front of the ship or would it just be really bright any direction you looked?

Something that I've long wondered about is about the implications within our brain and visual cognition of implanting bionic eyes that would process the entirety of the EM spectrum. What is the consensus of the scientific community regarding this hypothesis, would our visual cortex instantly...

We pick up things much more quickly if they are presented to us in a graphical manner instead verbally? Why is that? Basically I am looking for an answer in a neuro-biological perspective.

I know of the equation F=G((m1)(m2))/d^2. So the distance between two masses are squared then divided out of the out come of the masses times the gravitational constant. My question: how to make a visual representation of this formula?

My goal is to build a software program that simulates the function of the eye. As I (barely) understand things, a single photon can bounce off an object and enter my eye. Q1 - Does the photon determine the color? If not, what determines the color of that single wave/particle? Q2 - How...

Fortran / Visual Basic ?? I wrote more then few dosens programs in all flavors of Basics, mostly in DOS. Unfortunatelly with the new Windows systems, 32, 64 bit they are no longer usable. I would like to rewrite some of them. It is mostly structural engineering, cams, linkages. The codes are...

This is my first post to this forum, and it just so happens that what is on my mind right now is how the language and images that we use to describe our world, and teach others is a bit broken. I am not a scientist, but I've always been interested in it, and my interest over the years has...

Hi Folks, I have Google'd the above topic but I haven't found anything satisfactory. I am an engineer and I want to learn Visual basic programming (no programming experience) to enhance my excel usability. Can you advise any good online sources that is geared towards science engineering...

I wanted to do a demo of fractional crystallization that would have a nice visual result. I had intended to make a saturated solution of ferric chloride, nickel chloride, and sodium chloride, put the solution in a very broad shallow petri dish, and allow natural evap to produce concentric...

Hello everyone. It is exciting to discover your forum here. I am hoping someone might be able to point me in the right direction for finding any symbols, charts, diagrams, written formulas, et cetera (ANYTHING) that represents or communicates or otherwise serves to explain any of the...

Hello, I'm new to Microsoft Visual Studio and new to the C++ program. I just installed the program and I'm trying to write my first program. First error that I get is: ========== Build: 0 succeeded, 0 failed, 1 up-to-date, 0 skipped ========== Why is my project out-of-date? Second...

I'm first year ENG at a Canadian university where first year is general for all engineers. Next year I get to pick a field to specialize in. I'm really interested in computer vision, for example a system that could track a moving target or something. I Know this is crazy complicated but I'm...

Homework Statement Ok for starters, I wasn't entirely sure whether this was supposed to go under physics or comp sci, this is a 'physics' problem I believe but done through visual basic, anyways. So I have a program where the Earth is animated to orbit the sun based on Newtons laws, I need to...

hi,I am learning visual basic as a pastime. I have a question,I can plot positions in a 2 dimensional array e.g:- dim test(100,100) as integer for cox as integer = 40 to 60 for coy as integer = 40 to 60 test(cox,coy)=1 next cox next coy My question is how can I plot positions to make...

How do I write an algorithm for getting an A in my college physics class? Literally, is there a program that draw boxes an vectors to construct what one physically looks like?

Introduction For me it all starts with what I agree is counter intuitive: The Speed of Light The speed of light. An innocuous phrase. Stating a seemingly obvious fact that light moves at a particular speed, in the same way that anything that moves has a speed. Yet what does it...

This little test of templates and non-member functions works fine: // test5.cpp : main project file. #include "stdafx.h" using namespace System; template <class T> void mytest(void); int main(array<System::String ^> ^args) { mytest<double>(); mytest<int>()...

I'm looking for highly technical areas of science and math which are mainly visual in nature? Besides Physics.

I'm new to Microsoft Visual Studio (2010) & I'm a bit confused by the way Visual Studio handles fortran files. I saved a set of data in one console and tried to read the data from the created file in another console. I receive the next message: file opened correctly! forrt1: severe<24>...
