The Starliner's second attempt to fly unmanned to the ISS. Is it going to be a gigantic failure again? Is Boeing still a trash space company? Get the fuck in here and find out!!!!
I have a poisson distribution, whose is a log-normal distribution. So for example, I can randomly sample it >generate random sample from lognormal distribution >generate random sample from
But how do I calculate the CDF of this distribution? I'm only looking for numeric results.
I could do a Monte Carlo estimate, but that's gross. Is there a simpler method?
How do we revive Pythagoreanism as a religion? I literally want mathematics to be my religion. I want to worship numbers as the ultimate and supreme God and truth of mankind and all things in all of reality in every plane of being and existence.
Do you agree with this statement? What is wrong with it
In quantitative mathematical description of certain phenomena self-contradictory systems of equations are very often obtained, in which there are more equations than unknown quantities, e. g.:
{
x + x = 2
50x + 50x = 103.
The logical contradiction is patently obvious here, yet the system of equations is quite real. Its reality will become apparent on condition that x here denotes one dollar, and the addition of dollars takes place not only and not so much in the head but in the savings bank, too, which puts to an account three per cent interest per annum.
Under these concrete, and quite real, conditions, the addition of dollars is quite precisely expressed by the above ‘contradictory’ system of equations. Contradiction is here a direct expression of the fact that in reality it is not speculative pure quantities that are added (or subtracted, or divided, or raised to a power, etc.) but qualitatively definite magnitudes, and that the purely quantitative addition of these magnitudes produces at some point a qualitative leap disrupting the ideal quantitative process and resulting in a paradox in the theoretical expression.
I'm sadly bad at Physics and Math, sorry if I make mistakes here. Can someone tell me how to measure the vibration frequency of a crystal (e.g. quartz)? (I'm struggling with finding answers on the internet)
Is there any sci way how to fix ADHD sperg outs without meds?
I browse the web like 8+ hours daily and only work for like 20 minutes - however the deadline keeps coming closer and closer
just a quick one seeking advice on which course to take:
I'm currently doing a few modules from a distance learning university's maths course to gain some solid maths qualifications.
I have completed the first course which is essentially a recap of high school maths (basic calculus, trig, logs, series/sequences, complex numbers, matrices/vectors etc)
I can either take another foundational course or a second year course.
The foundational course has the following syllabus:
number theory, conics, geometric transformation, mathematical language and proof, further calc, differential equations, mechanics, eignvalues and eigenvecotrs, combinatorics
the 2nd year course has:
differential equations (1st order, 2nd order, systems of, PDE, nonlinear), multiple integrals, linear algebra, fourier series.
I come from an economics background, so the latter course seems more relevant. but im interested in dabbling in computer/data science, where things like number theory and combinatorics seem more relevant.
