    Physics Navy or Air Force for Particle Physics

    I served in the Army for a decade (infantry). I do not get the impression that you have done enough research. You don't stay in the military for every how long you want (ie until you find a better job or decide to go back to school) you stay for the 4-6 year contract that you signed. Also, I...

    Engineering Would you take a job not in line with career goals?

    it's nice to feel wanted. When I was younger, I applied for a job on a whim because I was a bit bored at work. I wasn't typically bored at work but it was a slow season for us. Anyway, I happen to get a reply and decided to interview just to see what it was like. Fast forward a few weeks, I...

    Engineering Applying again to the same company

    Yeah I concur with CrysPhys. I've worked at fortune 10 companies and small 50 people size companies. At large companies it's pretty tricky. It's common to see two "Analyst" jobs within an analytics group show up on a job page. While some may assume that because it's the same job title and...

    I Question on Actuary Exam -- Error?

    Typically actuarial exam question. Given that someone is 90 the probability they live until 91 is .8. Probability someone who makes it to 92 is .48. .8 -.48 = .32 so .32 die before reaching 92. Repeat this procedure over and over again and then sum each term with respect to the age, you'll...

    Programs AI or theoretical physics

    I've worked most of my career in financial services to some degree or another, so I can't speak for many sectors. I did for a few years worked as a Senior Data Scientist for a large telecom. Hours there were generally more traditional and the pay range was from 100k-180k + pus 10%-20% bonus...

    How much money can you make in physics?

    Yea, we typically hire fresh PhD at the 250k range, to get to 500k, you have to have lasted for quite a few years. Most PhD on our staff last typically 2-3 years before they are stolen (thus the high pay) or burnt out. Also, we're based out of NYC so cost of living is a bit higher than the...

    Programs AI or theoretical physics

    I tend to encourage people to spend 1 summer doing an REU and 1 summer doing an internship. I find that this really helps define if you actually like "research" or the "idea of doing search". I've had a few undergraduates who had full intention of becoming researcher in something, but during...

    Programs Don't like my calculus class, but want to be a math major...

    If you can solve those problems, and interested in theory then Math major will probably be ok. Keep in mind that you should expect a few courses similar to plug and chug even if you study math, but as you progress the level of abstraction should increase. As a side note, whenever I was bored...

    Physics Physicists and physics majors, was it worth it?

    People who cannot find value in their experiences, are definitely people not worth hiring. Therefore, yeah I agree your RA is useless for you, but not because it's useless. Maybe you're right, nothing you learn will directly apply to whatever job you think you want (doubtful), but maybe that's...

    I Spectrum classification and dimension reduction

    Broadly speaking high dimensional data can be problematic for two main reasons. First, the computational cost to learn and inference may be high and secondly it can lead to over-fitting. Dimensional reduction attempts to resolve these two issues while still preserving most of the relevant...

    Financial Knowledge All Adults Should Know?

    I would say the number you would reasonably need is near 1 million to honestly live off of your interest. First, 10% year after year growth is absurd. Does it happen sure. Does it happen reliably? When you want to live off of your saved money, you typically want your assets to be more...

    Other What to do in your job search if you've been fired

    It's not the end of the world if that is the concern. I've found that a star employee at one company can be the redheaded step child at another one. Sometimes, two companies, with different cultures, values and responsibilities may get different output from different employees. I once left a...

    PF Investing Club

    Sure, however no one speaks of short term trading in that functionality. Short term trading is taking a position for a "short" duration me it minutes or days or even weeks with the hopes that you beat a correction. ETF maintain their positions but have to rebalance their leverage ratio...

    Not in this sense. Daily trading or short term trading is simply trading for short term positions. ETF rebalancing are not trading to change their position but to correct the leverage ratio that is occurred with gains.

    I concur. Betterment basically uses algorithms to buy ETF and automates the risk pool allocations. It isn't a leap to think algorithms can take in earning statements, and market conditions as inputs and make stock selections as well as your common day trader.
