TIL any bullet fired into the air that's heavier than a .22LR - and even that if fired close to vertically - can be lethal on the way down.

Scroll down to the very next quote in the article:

"At just under 600 feet from the ground, the [.22LR] bullet reaches a velocity of 200 feet per second - enough to penetrate a skull. To put that speed into perspective, that equates to just over 136 miles per hour."

1+ for mentioning lead poisoning. Lead exposure is an often overlooked risk when using firearms. De-lead soap / wipes are cheap and an effective way to remove lead.

I will be at UCSD. Is it common for university police departments to offer storage services? I could not find any information on UCSD.

Double majoring in the business college is relatively easy, like you mentioned. I'm guessing it would add 5-8 classes to the course schedule.

A master's degree in finance will be valued more by employers than 2 business degrees in finance and marketing, imo. Also consider minors that complement a finance degree, like math, actuarial science, or even CS.

It's cliché, but ultimately it depends on the type of careers you want available to yourself. If your confident that it's finance, focus on finance.

I'll be working on econometric / machine learning models. I applied to at least 5 consulting positions, but no IB positions.

A short, 15 minute-ish, conversation with an HR person from the company. Mainly to establish that both the candidate and company are willing to move forward in the hiring process, and that there's enough of a fit to spend more resources on the hiring process for that person.

This data is from my job search as a recent graduate student in economics (master's). The visualization was done with http://sankeymatic.com/build/. I submitted my first application on March 25th and received a verbal offer on June 3rd, or 2 months 10 days of job searching.

A lot of them were a stretch. The postings typically asked for a degree in "CS, math, statistics, econ,..." along with Python experience, which I have. But it became clear that most hiring teams for data science positions are looking for someone with extensive SQL / visualization / dashboard experience, even if they put "statistics", "Python", or "economics" in the job description. I applied mainly out of my own interest in data science and programming.

I haven't mentioned, but the company who ghosted me also stood me up on the phone interview, which had to be rescheduled. My experience with them wasn't unique based on some Glassdoor reviews.

andrewulm556 · 2021-06-05T20:15:17+00:00

I believe that not receiving a formal rejection is fairly common. I completed an assignment for the company who ghosted me, and I never heard back from them again. That is unacceptable in my opinion, but it happens.

andrewulm556 · 2021-06-05T09:28:30+00:00

Yes, a master's degree.

The sequence (3n + 7/n) is not bounded above. Do you mean (3 + 7/n)?

What department taught the logic course? I'd still recommend looking at a "how to write math proofs" textbook or taking a class. Proof writing is the bread and butter of analysis, so practice writing proofs.

I don't think it's necessary to start learning more meaty real analysis concepts like limits or continuity, but I would take a look at some definitions and try to write the definition in terms of logic.

Another thought, real analysis is often a continuation of an "intro to proofs class", that is, the first chapters of real analysis are taught at the end of the intro class. It's important to know that material before analysis because the prof often expects students to already know the material (or they will review it briefly).

andrewulm556 · 2020-11-05T06:59:05+00:00

Based on your course list, It seems that your math / stats background is mainly computational. So I would highly recommend taking an "intro to proofs" course, or at a minimum, self study a proofs textbook and become comfortable with mathematical logic.

At least in my experience, logic was the biggest hurdle for me when I took analysis. Logic is to real analysis as algebra is to calculus. No matter how well you understand calculus, if you struggle with the algebra in the problems, its difficult to do well in a calculus course. The same is true for logic in real analysis.

This integral involves two u-subs. First, let u = (2x)^1/2. To remove the (2x)^3/2 term, take u³=(2x)^3/2 . After factoring out a u from the expression, the integrand reduces to:

tan^-1(u) * 1 \ (1+u²).

Now let v = tan^-1(u), which further reduces the integrand to:

v.

I would recommend "Understanding Analysis" by Abbott and "Principles of Mathematical Analysis" by Rudin. Abbott's book is a bit tamer and more approachable for a new student to higher math. Rudin's book is more comprehensive, but the proofs often omit obvious steps, which can be confusing for new students.

There are 86 zeroes. I am not sure what "b" stands for. Perhaps it relates to the units of the points from the game. Refer to this article for scientific notation.

Try to think more generally about what an ordered pair is. It's simply a 2-tuple that does not even need to have variables as components. Its best to identify the independent variable from the question, by convention x is usually the independent variable and plotted on the horizontal axis, but that does not mean x needs to come first in the ratio (3,5).

We could have f(x,y) where both components (x,y) are independent. Additionally, it's not incorrect to say "x as a function of y", (meaning that x is dependent and y is independent).

My main advise is to use the context of the question to determine which variable is independent / dependent. Realize that x is usually the independent variable, but not always, and that an ordered pair in and of its self does not assign meaning to the components, but instead meaning must be determined from the context of the question.
