He's right about Sabine but he's not an actual professor and his knowledge is very surface level.

>in real math, that is, physics
They are important everywhere.
Look at quadratic, cubic, and quartic formulas. If you "pretend" the coefficients have units (so that each monomial in the polynomial is the same unit), you can almost cook up the formulas by guessing since you know which things can be added and which cannot and what the unit for the solutions is.
The units in physics are a kind of type system. Math and CS have gone beyond the simple stuff in physics.
Don't DK yourself

>3. Parenthesis to enclose arguments of a function AND enclose parts of an expression.
This is easily the worst convention. There's not much real reason to not just have function application use square brackets like f[] or just *something* different from parens so that there's some basic difference and multiplication cannot be confused with applying a function in situation where there's any potential ambiguity.

A lunar lander in the last few days successfully tested Earth-based 4G communication, which will enable high quality video within CIS-lunar space. So yeah, Internet in space.

To answer your original question: The next step, beyond sending scientific probes, is building infrastructure. It will be analogous to the trans-continental railway replacing the wagon train, transforming an arduous and dangerous journey of months into a couple of days (with continuous boost at 1g thanks to a fusion drive, and even more: an orbital ring slingshot at either end, that not such a stretched analogy).

It will affect you because it will mean living in an open-ended universe instead the gravitational bottle of ZOG.

NTA, but i had a hiccup proctoring a computer architecture class exam when i presumed that the class had gone over all common arithmetic flags found in any ALU, particularly the overflow flag.
kids were bewildered, and i panicked in front of 200 kids and called the prof to ask what to do. i can't remember if i reached him.
i ended up having to say you can use it if you understand it, or you have to create a circuit to solve whatever problem was at hand.
i could have handled it better, but there was no issue when grading came up.

evidently i taught myself about computer arch more thoroughly by dicking around and hacking vidya than a top tier CS program teaches its kids

>https://english.elpais.com/science-tech/2025-03-05/new-inheritance-mechanism-unrelated-to-dna-is-discovered-by-chance.html
>New inheritance mechanism unrelated to DNA is discovered by chance
A study originally focusing on cancer has shown that amyloids — proteins typically linked to neurodegenerative diseases like Alzheimer’s — influence inherited traits. The discovery could, say the authors, explain part of our ‘missing heritability’
>Amyloid proteins can be very different, but they are named after a certain structure they form when they fold. And they have a very peculiar characteristic: they have the potential to multiply by “infecting” other similar proteins with which they come into contact. This “vampirization” is the way prions, which are essentially another type of amyloid protein, spread. Although their reputation is terrifying, their characteristics also allow them to play important roles, such as in the storage of hormones or possibly also in the formation of memory. And, as Harvard University professor Craig P. Hunter writes in a text about the new discovery: “In the same way as DNA, amyloids replicate themselves using themselves as a model, which makes them ideal carriers of acquired, inheritable information.” This, which had been seen in yeast, is now being confirmed for the first time in much more complex animals.

>"but FTL travel would cause time paradoxes!!"
Not necessarily. Firstly, this would imply that the time dilation effects at exactly lightspeed outright stop time, which is obviously not true. Moreover, the only thing the formulae imply about causality violations is that if speed can keep going up indefinitely, then eventually you will get a paradox. However, what speed is that? Going 1mph faster than the speed of light doesn't cause time paradoxes.

We can already observe FTL in our universe: if light can't even escape a black hole, that means the black hole has opposite inertial forces greater than the speed of light.

>>16608641
The slope can only change if you are going sub c you fucking retard. This is high school level geometry just draw the worldlines to see that! At c you have no slope and don't experience time because there is no light's frame of reference.
In relativity you assume c and no light's frame of reference, you can't change it and still use a model based on these assumptions.
