    Becoming a meteorologist

    That's my current occupation. I was big on software for maybe 10 years and that's what my degree is in. My interests have changed a lot since then though, and meteorology/weather has always been a hobby.

    Becoming a meteorologist

    My degree is in math with computer science (theoretical CS for the most part with a strong math background) with a minor in earth, atmospheric, and planetary science. I have a master's in computer science.

    Becoming a meteorologist

    I have a software engineering degree but I'm thinking of changing careers. What additional training do I need? Where do I begin? Do I have to go back to school? Should I get involved with some weather forecasting group (at least amateur weather forecasting)?

    Becoming a meteorologist

    Statistics? Why statistics? My actual degree from MIT is actually math with computer science (so I've got a strong math background).

    Becoming a meteorologist

    Hi! I was wondering what the best way would be for me to transition into a career in meteorology. I have a minor in earth, atmospheric, and planetary sciences from MIT (and would have probably become a meteorologist had I realized MIT had a degree in it!). My actual degree is in software...

    Integral of sqrt(1 + x^4+ 2x^2)

    Here's a bit of a hint. When you expand (x+1)^2, what do you get?

    Steel bar bisected by event horizon

    Hi! There's got to be something wrong with the following method to take photographs of the area inside a supermassive black hole, but I can't figure it out. 1. Lower your spacecraft to just outside the event horizon. 2. Extend a uniform steel bar with cameras embedded in it through...

    Superman's Helicopter

    Another thing to keep in mind is the fact that the "signal" that the rod is being spun has to propagate down the length of the rod. There are actually two things to keep in mind here: the speed that the end of the rod is moving at and the speed at which the signal is propagating down the end of...

    Superman's Helicopter

    Hi! I'm sure this has been done before, but here goes. Superman is flying through the vacuum of space and stumbles across a rod 100,000 kilometers long. This rod is of nonzero mass and is narrow enough for him to hold in his hand. It is infinitely rigid, with an infinitely high shear...

    Can dark matter travel FTL?

    But is it possible that there are certain laws of physics which dark matter does not obey simply because of the way it works? Perhaps it obeys some of the laws (gravitational, for example), but not others (such as the c limit). I'm not even sure we know enough about dark matter to rule out...

    Can dark matter travel FTL?

    Hi! I'm sure this has been done before, but is it possible for dark matter to travel faster than light (at least some candidates for dark matter)? We know that ordinary matter is limited by the speed of light, but what about dark matter? For all we know, dark matter may not use c-limited...

    Unusually long-lived Painted Lady butterfly

    Hi! I'm not sure whom I should talk to about this, but here goes. My girlfriend and I got a bunch of Painted Lady butterfly caterpillars (second instar at the time) from a conservatory the day after Valentine's Day. According to what I've read on the Internet, the butterflies should live...

    Expected length of longest winning streak in a 162-game baseball season

    Correct. However, as you know they're far from independent. If game 11 is a loss (50% chance) then there's no way for the set of games ranging from 2 to 11 to be the start of an 11-game streak. That dosen't sound like it will work. ACG

    Expected length of longest winning streak in a 162-game baseball season

    Hi! The Red Sox just finished an 11-game winning streak, which made me wonder. Do most teams experience winning streaks this long over the course of a season? What is the expected value of the length of the longest winning streak for a .500 team over the course of a season? In...

    Gas around the black hole of galaxy M87

    A spacecraft creates two entangled particles. One of them falls into a black hole, past the event horizon. Inside the black hole, the entangled particle interacts with a piece of matter (and if all else fails the singularity). This forces a measurement on it. Does the wave function...

    Escaping from a black hole

    Hi! What's wrong with the following method of seeing what life is like inside a black hole and escaping? I can't see anything obvious. We'll assume that time scales and tidal forces aren't an issue (it's obviously impractical -- but is it impossible)? 1. Get a spaceship which can...

    Traffic lane selection problem

    Changing the time at which the driver leaves may not do much either. Remember that all of the other drivers are logical. If they all realize that the traffic at 8:30 jams up, they'll figure to go at different times. So they'll all go at 8:15 and the traffic will jam up at 8:15 instead :)...

    Traffic lane selection problem

    Hi! I've been dealing with a situation like this for a couple of years now and it made me start thinking... A city is populated entirely by infinitely logical drivers (I know, it's hypothetical :) . This city has two major N-lane highways (N > 1) which intersect each other at a...

    Earth may get hit tommorow

    I'm curious if it's possible to figure out what type of object it was from the data we received from the collision. All the reports were saying it was coming in at 12.8 km/sec. It released an energy about 1.1 to 2.1 kT of TNT. It was also reported to have been 3 meters across. We've...

    Is it possible to determine if a photon is entangled?

    Hi! This may be a stupid question, but here goes. Is it possible to do a measurement to determine if a photon's waveform is entangled with another photon? You don't need to know who it's entangled with, and it's all right for the measurement to disrupt the entanglement. If this is...

    New ideas for programming languages?

    Hi! I've got a couple of new ideas for programming languages. I'm curious if anyone has thought about these. 1. I was thinking about AI and it just occurred to me -- is there a programming language which has AI built into it, much as like traditional programming languages have assembly...

    Unusual object I saw in sky in Boston area

    Hi! I just saw something very unusual in the Boston sky today at 4:00 PM. Yes, in the middle of daylight. It looked a lot like a star and it was almost straight up. It then slowly moved roughly from west to east and went maybe 45 degrees in 5-6 minutes. That would give whatever it is an...

    Extension of Fermat's theorem?

    Hi! That's cool -- I'd wondered about that myself :) However, that won't help here: the sum of four objects case would have to be a^5+b^5+c^5+d^5 = e^5. ACG

    Extension of Fermat's theorem?

    Hi! I assume you all know Fermat's last theorem. Well, has anyone considered the following extension to it? Assuming we're just using integers: We know that x1^n + x2^n = y^n has no solution for n > 2. However, what about this? For which values of k does x1^n+x2^n+...+xk^n = z^n...

    Prime question

    Hi! I was thinking about primes and have a bit of a question. I apologize if this is too easy or obvious -- I haven't thought much about it. Take two relatively prime numbers, P and Q. P < Q, and P is not prime. How many pairs (P,Q) are there so that ALL positive integers which are...

    $10B international prize to find something which will stop/halt/global warming?

    Hi! I just read that Richard Branson or someone like that offered $25M to someone who was able to do something which would reverse global warming. While that's admirable, it just seems to me that it's too low. It would probably take millions of dollars to simply do the experiments etc. to...

    Sedna must be a planet (at least for now) according to new definition?

    You also have to consider the following: Sedna's orbit is highly eccentric, so the rule about it clearing out all of the mass in its vicinity doesn't make sense. If an object is in a circular orbit, it's fairly obvious what its neighborhood is. But if it's eccentric, the idea of a neighborhood...

    Sedna must be a planet (at least for now) according to new definition?

    Hi! I saw the definition of a planet -- basically anything differentiated that has cleared everything in the area and orbits the central star. Pluto doesn't count because it's in the middle of a belt. Ceres doesn't count because it's in the middle of a belt. Sedna -- well...

    Program to bring together gifted science students and mentors?

    Sounds like we have enough support to make me think about getting this off the ground. All we'd probably need is a website at first and publicity. ACG

    Program to bring together gifted science students and mentors?

    I haven't thought the logistics through completely yet. However, I figured the mentors would put their resumes and so forth online so that the children's parents can look at them. I hadn't thought of it being necessarily for financial gain. It would just be for volunteer work for people...
