    Optical Transistor

    I was recently looking in lasers and and their uses and while watching Cosmos with Newton using a prism to shows the different colors of light from white light i got thinking. I stumbled onto the top optical or photonic computers a while ago and I decided to look into building one. After...

    RF Ciruits and Microwaves

    My school offers a concentration in RF Circuits and Microwaves in their EE program. I have an idea about what some potential jobs/careers that use these topics are but am not sure. Can anyone tell me more about the concentration are/field and what jobs would be available in it or what some...

    News How far should the Dragnet reach.

    I have a big interest in history and world politics, and now when i look at the US they denounce other countries for monitoring and censoring the internet and right of others but are some of the worst offenders themselves. Sometimes I will end up worrying that just in a Google search that the...

    Mars in the future

    Mars does not currently have a thick enough atmosphere to allow water to flow and also due to extreme temperature variations. If if more CO2 was released from the ice caps I doubt in would be fast enough to help build up the atmosphere and would get stripped away possibly from the solar wind...

    Testing GRE Physics Prep Courses

    Hi all, I will be a freshman in college starting this fall at Worcester Polytechnic Institute and am majoring in EE with a concentration in RF circuits and microwaves along with a possible double major in Physics with a concentration in Electromagnetism. I am looking to work with EM after I...

    Theories of the origins of the universe

    Another idea is to add disproved theories on the origins of the universe such as the steady state theory which says the universe is infinite and always existed. Olbers paradox could be included here for support on why the universe is not infinite. The thing is that even with different theories...

    Riemann Zeta Function Zeros

    I was looking at the Wolfram Alpha page on the Riemann Zeta Function Zeros which can be found here, http://mathworld.wolfram.com/RiemannZetaFunctionZeros.html At the top of the pag there are three graphs each with what looks to be a hole through the graph. Now I know the graph is an Argand...

    A rudementary question on dark matter

    The existence and location of dark matter can be inferred by gravitational lensing. It is one of the best ways we have to locate it but even then it's not easy. I do remember a team of astronomers created a map of the dark matter, if I find it ill link it. However dark matter is still classified...

    Where those energy go?

    The energy is not stored in a specific place but rather goes into the environment as heat and light and so it increases the entropy of the universe. It is not destroyed but merely the energies form is changed.

    Schools High school student doing college physics . need help

    Keep practicing your math and strengthening your problem solving skills. This will reinforce your knowledge and make you better at the math and so the physics. You need a solid background in the math before delving into even more complex physics.

    Another seemingly easy forces question

    The force thought with 150N has three significant figures. Leading zeros are not included in significant figures but trailing zeros are. The right answer was found but on a test it is always best to account for significant figures and I have always been expected too. Here is a link on a brief...

    Will there ever be a 2nd ice age?

    The earth seems to go through periods of warming and cooling and those periods of cooling can bring an ice age depending on the temperature change. We will go into another ice age, the correct answer is we don't know as we cannot predict the future but the most likely explanation is yes but the...

    Another seemingly easy forces question

    The blocks acceleration is 2.53m/s^2 which is three significant figures so an answer of 37.5kg is correct. Just don't forget the correct units.

    Solve for x 5/3 = 1/2(x^-1)(y)

    You are trying to solve for x so my approach would be to solve to y in terms of x and then plug that into y so there is only x in the equation and then solve for x, so 5/3 = 1/2 * x^-1 * y Multiply both sides by x as you did before 5/3x = 1/2 * y Divide both sides by 1/2 10/3x = y Now plug...

    Cosmic Strings

    The paper was helpful and interesting so thank you, I saw as I was reading it, it might be possible to locate the strings theoretically in the real world. Besides what is in the paper would any of you guys know how this could be done.

    Cosmic Strings

    I have reading about cosmic strings and have some questions about them, are they in any way related to other dimensions even though they are one dimensional? Also do they have anything to do with gravitons and the cause of gravity?

    Planetary system being born

    We must remember what we see is millions if not billions of years old and since then star formation may have slowed along with the formation of planetary systems. This paper http://www.naoj.org/Pressrelease/2012/11/05/index.html proposes that the universe has already made most of the stars it...

    Stargazing Radio Telescope Question

    If you want a small radio telescope I found this: http://www.haystack.mit.edu/edu/undergrad/srt/index.html, it gives details on how to build a radio telescope along with some projects for it and instruction Manuel and parts list is on the site. Would be interesting to build.

    Interesting simulation of a spiral galaxy evolution.

    Do you know how they created the stimulation? Was it a custom program or one already made?

    Schools Complex Analysis in High school

    How did you study and grasp calculus before taking algebra 2 and trig, they provide essential information needed to understand calculus. Also you can get cheap textbooks by older older ones even online, once a semester is past textbook prices will start to drop like a rock as new additions are...

    Programs Which majors for my interests/criteria?

    I would suggest electrical engineering based on your interests. It uses both math and physics as you want, and applications for the discipline are abound. It would allow you to work in the energy industry or space industry, check SpaceX's website and you will see that they need electrical...

    Engineering Accelerator Physics and Engineering

    What roles do engineers play in the field of accelerator physics, specifically electrical engineers. I would imagine something to do with electromagnetism or microwave engineering but I have no idea. Does anyone else know what they do in the field? Thanks.

    Amateur Exoplanet Imaging

    Is it possible to detect exoplanets with amateur telescopes? If so what size would be needed. I have seen some amateur protoplanetary disks pictures and would one be able to tell if an exoplanet existed in it as I carved out the material for planet formation? Is it possible for us with current...

    How many questions do you have a burning desire to know the answer to

    I have many questions but these are the most important: 1. How do girls think. 2. Who am I and who are you? 3. I have infinite more questions, and before you say I can't have infinite questions, when I find the answers to current ones then I end up with more.

    And somewhat more than a quote, but my favorite and in my opinion a humbling one: From this distant vantage point, the Earth might not seem of any particular interest. But for us, it's different. Consider again that dot. That's here. That's home. That's us. On it everyone you love, everyone...
