Hey guys. I'm wondering if this is too heavy of a course load. I am studying construction management, but I'd like to minor in mathematics. I really enjoy math and science, and do well in all my classes. I want to finish the calculus series, but after this quarter I will not have the time. To...
This question is directed to all the professors who have supervised PhD students in high energy theoretical physics.
What attributes have you noticed (during your years as a supervisor) among PhD students who later went on to have great careers in high energy theoretical physics and made a name...
I've been accepted to Cornell Engineering, and am thinking about doing AEP. I really like physics and math and was just wondering what people thought of it. Yeah I know I should ask people at Cornell, but they're just going to tell me that it's awesome and I should do it. I want to get a more...
I was fortunately accepted to a strong graduate program today. It really is a great program (e.g. top 25 ranking in Physics/Astronomy) but was largely a secondary plan. I will call this option Program B.
My main goal has always been to pursue a career in a very different field and I am still...
Isaac Newton imagined a bucket of water suspended on a fine (ideally torsionless) rope, set spinning. Friction eventually causes the water to rotate along with the bucket. The surface develops a dip in the middle and rises at the edges owing to the water's inertia. (You see this effect every...
It's been years I don't have a desktop pc and now is the time I "need" one. My use will be numerical simulations, compiling general programs as well as latex documents, some lightweight/middleweight programming, using a virtual machine and use another OS's this way. I'll be using Linux only. My...
Homework Statement
The Observer (me) is at Inertial Frame of Reference:
1)
I am sitting at a car moving east v=30 km/h relative to earth
A bird flying east v = 10 km/h relative to earth
What is the speed of bird for me?
2)

I have been in a heated discussion with my acquaintance about natural selection. Anyone who thinks natural selection is a real thing any links would be helpful
Now in the pop science news is about how "disco balls" could be the key to interstellar travel.

What do you guys think of this project? Its feasibility, cost, usefulness etc..
Hello,
I've heard about "H.M." and similar patients that lost the ability to create declarative memories, but can still create non-declarative memories.
I was wondering, since one in this condition can for example, develop a habit of drawing complex shapes, and not know they did it, can they...
Hi all! I'm an undergrad sophomore in engineering trying to decide on which major to pursue (namely civil/mechanical). Recently I came across this fascinating piece of publication, which contained a massive amount of data regarding engineering enrollments by major, demographic, and school...

I've had a pretty poor experience going through the standardized education system in California, and now that I'm in college, I'm really fed up with how mathematics is taught (even at the college level). With this said, I thought it would be fun for me to redesign the entire math education...
I am taking the physics praxis (5265) in about a month so I can add to my bio/chem certifications. I'd actually prefer to teach physics even though I went to graduate school for environmental science.
It has been fairly difficult to get good info on the test -- I've taken the practice exam...

I saw this antenna matrix on the north coast of California this week on vacation (a couple miles north of Half Moon Bay). It's located about 1/4 mile from the beach on Highway 1. There is a powerline running past it, but it looks to just be getting much of its power from a trickle charge from...
Atmospheric sciences are—much like the sister science of astronomy—primarily observational sciences and not primarily experimental sciences. The atmospheric systems that we study are not well-defined systems under controlled conditions, but ill-defined systems under completely uncontrolled...

Quantum Holonomy Theory
Johannes Aastrup, Jesper M. Grimstrup

We present quantum holonomy theory, which is a non-perturbative theory of quantum gravity coupled to fermionic degrees of freedom. The theory is based on a C*-algebra that involves holonomy-diffeomorphisms...

Science, unless I'm mistaken, tells us that electrochemical exchanges within our neural networks are what dreams and thoughts are manifested from.

Here in Missouri, MST has a very good academic reputation, but it seems this is not true everywhere. This is all wildly imaginative at this point (HS Senior), but if I were to major in physics at MST, (assuming I made good grades), is it unreasonable to hope to get into grad school at some of...
How we are able to recollect things and how random thoughts are generated in our mind?

I've seen a previous threads where it was a mathematical consistency based on four-dimensions, and a host of other reasons. I'm currently trying to reconcile my belief that it has to do with time dilation and the observer effect.
I just finished reading a book called Three Roads to Quantum Gravity, and in it the author mentioned a few arguments surrounding quantum cosmology. He did not seem too fond of it, but to me (relatively inexperienced) combining the two makes a lot of sense. What are your thoughts on it?
In re-discussing the EPR scenario in his autobiographical notes (1946), Einstein wrote:

But what if, at Place A there was...
