Hey guys, i really need your help on this. I completed a 3 years BSc in physics in april 2013. However i am not at all satisfied with my preparation (the teachers at my college were hardly interested,yes that's the state of pure physics in my university!). I am planning to take a gap of a...

So I have been reading this forum for a while and I have heard more than a few people say things like the employment rate for physics PhDs is worse than it is in the humanities and way, WAY worse than for med school, so that doing a physics PhD as opposed to a med school degree is a huge...

I still want to be a physicist. I want to go back to school next fall, but haven't really made plans yet. I went to university for one year after high school, failed one semester and withdrew the next before being kicked out of the dorms for smoking pot. The next 3 years I attended a local...

Dear all, I genuinely cannot fathom a reason why most universities have a strict policy against hiring postdocs with five or more years of postdoctoral research experience. Could somebody please elaborate? I cannot imagine anybody benefiting from this arrangement. 1. Universities and...

As outlined in this article - http://nz.finance.yahoo.com/news/anniversary-great-recession-whats-changed-145605229.html - today marks the fifth year in which the financial crisis 'started'. I quote 'started' as the initial lead up occurred when those with very terrible credit ratings were...

Greg Bears Book one: Anvil of Stars Book two: Forge of God Anyone else a fan of these books? I guess I am just a hard scifi addict.

Afternoon all, just a general question I'd like to ask and I'm interested in your responses. Look how far technology has come in the last 70 odd years. From the first black and white tv to HD flat screens. From propeller driven planes to stealth fighters. From the Z1 computer to the modern Intel...

The Battle of Gettysburg was the decisive battle of the American Civil War, fought from July 1 to July3, 1863 just south of the Pennsylvania town for which it is named. It was a Union victory but the southern commander Robert E Lee escaped with a good part of his army intact. The war would last...

I dropped out of UCLA about 10 years ago. Have done some real estate since but nothing much with my life. I'm planning on going back this year and getting my bachelor's degree. I'm now 33. Yea I know. I screwed up by dropping out and not finishing what I started. But I guess now is better than...

The first stars formed when distances were 9% of their present size. The solar system began forming when distances were 70% of what they are now. Andromeda galaxy will make a first pass through Milkyway when they're 129% of present. Which do you find more meaningful and intuitive for...

That sounds pretty obvious. But it wasn't because of the interpretation of evidence. The charcoal / soot required as evidence was not available. In a nutshell. Robertson et al 2013 explain that it was merely a misinterpretation. The charcoal is simply dilluted by the debris from the...

Next year, I'll be a full time student. Due to poor planning on my parents part, the amount of money saved for tuition and other university costs is not as high as it should be. In order to avoid having to ask my father for money (which he wouldn't be too keen on giving me), I've been thinking...

I'm 26 years old , been thinking about going back to school for the last 2 years to pursue a career in mathematics. Never went to college , stopped my education at the end of high school where I had multiple personal problems that are now more or less solved.Always been strong at math since I...

How big was the Universe 13 billion years ago?? If we look from the Earth, in opposite directions, at objects that are 13 billion LY away, they are 26 billion LY apart. We are seeing them as/where they were 13 billion years ago, so they must have been 26 billion LY apart then. This...

Is it possible to use celestial coordinates which were taken 50 years ago? What kind of inaccuracy can we expect (give the answer in degrees)? Could I say that it will be about 0.3° error assuming that around the year 130 BC, Hipparchus compared ancient observations to his own and concluded that...

Light years-I just don't understand how something as subjective as visibilty, is used as a major indicator of distance. Isnt that subjective. What if some species had a million times the eye power than us humans, wouldn't they view the distance of let's say stars very differently because it...

Or more precisely from advent of the gramaphone and "talkies" until today. I am geussing it is 4 beats per measure, but why? I am asking with respect to how iambic pentameter could have become predominant back in the day, if poetic meter is ultimately derived from musical time, as that would...

I was originally a Physics major going to start my upper-divisions in the fall. However, a couple days ago I talked with a civil engineer and was genuinely interested. As of right now, I went and reviewed thoroughly much of my lower division physics and math courses courses (up to quantum...

says that computing power at an economic price roughly doubles every year. this relies on the fact that we can stuff more transistors into smaller spaces. we won't reach quantum limitations until atleast 50 years. where will we (humans) be by than?

if the first known human fossil is 200k years old why the earliest known human civilisation is just few thousand years old? Why there was no reasonable developments for a very large time like 190k years?

Hello to all, I have been out of high school for some time now, since 1994 to be exact. So in 18 years I haven't had any direct contact with any algebra or any such math in some time. Actually I can't remember the last time I was asked to do an equation; until now. I'm currently at a CC and...

I'm a sophomore in HS and am planing to go into nuclear or astrophysics. I am wondering what I should be doing in preparation for going into these fields? I am in honors chemistry and honors trig/pre-calc (with 98% in both classes) this year and will be taking AP Calc and physics next...

There has been a series of papers recently published that provide observational data that indicates that something is cyclically abruptly changing the geomagnetic field. The rapidity of the observed geomagnetic field changes cannot be explained by a core based mechanism. There is no...

"Radioactive waste will stay dangerous for hundreds of thousands of years" There's one statement which's always used by people opposed to nuclear power - that the waste will stay dangerous for thousands, ten thousands and even hundred thousands of years. But I'm wondering - is this accurate...

Hello, so due to my job contract I cannot return to college for 4 years. I only graduated with a 2 year degree in business and want to go back to do an engineering degree.

Well today I was reading much about the subject of light and photons.And we agree that photons are massless and taht is the reason they travel at c. But if something travels at c then it means it has no time as is said and if that thing traveling at c has no time then it means for a observer...

About three years ago or so, I came to this site complaining that for the life of me, I couldn't pass calculus 1. I just couldn't grasp it. I thought I was bad at math, couldn't do it, and was destined for something far less. Fast forward to now and I am about to graduate with a double major in...

Hi, I have just a few basic questions. I was in the army for about 6 years then worked as a CCNA for about 6 years before being layed off, entire company was farmed out to Philippians I believe. I am a disabled vet with a wife and 2 year old. I was accepted into the VA's chapter 31 program...

I've given this a lot of thought the last couple days. I look at the Hubble equation v=H_0 d, and I don't see how this necessitates everything existing in a single point at some time in the past. Certainly, everything was really close together 13.7 billion years ago, but not in an infinitely...

It's been bugging me. We've looked 13.5 billion years into the past, supposedly only about 500 million years short of the big bang, at objects 46.5 billion light years away. What were the limiting factors? What stops us so close from the finish line from peeking into the very beginning? If it's...
