Corruption. See if you're able to report the cheating students directly to the Academic Integrity Office or whatever your university's equivalent is. Talking to the department head might be a good idea, but it's also risky depending on the details.

Don't expect anything to happen to the professor, but a message of "I'm not just going to let this go" is far better than nothing at all. If people start to get away with cheating, it snowballs like mad.
>>
>>9369809
Sadly, that's not always true. Plenty of people cheat and still manage to flourish in life. If you cheat constantly, you're not likely to get anywhere in life because you eventually won't even know enough to understand harder material even if you tried. But I think the majority of cheaters don't cheat consistently and they probably take steps to avoid being caught.

I may have cheated occasionally in college but my test grades were fine. I don't like having to do the same type of problem repeatedly after I understand the concept. That issue wasn't as bad in upper level undergrad mathematics but it still occurred occasionally. Sometimes I didn't even have the time to do all the homework either but I needed the points. At least my focus was always on understanding the material sufficiently, even if I cut some corners.

Good for you managing to get by without cheating though. I envy your discipline and drive.

Stop wasting your time, giving your tax money, wasting your attention on any space agencies. They are all fraud, obviously.
How do they manage to keep the secret, if every space agency has 200+ workers? Who fucking knows. Maybe it's "money talks, truth silences" thing...

You can totally view division as repeated subtraction. To divide x by y, start with a group of x things, take away groups of y things (i.e. subtract y) until you run out (i.e. reach 0). How many times did you take away a group of y things? That's the value of x/y.

What's the point of settling on Mars?

It's gravity is so low that humans will never be able to reproduce there. People will have to move back to Earth to have kids or there will need to be a giant rotating space station built in orbit for people to have kids on and for the kids to grow up on.

Why do people think it's possible to colonize it when this issue exists? Visiting it is fine, but living there is a non-starter. Are the people who support Mars colonization pop-sci redditors with no understanding of this issue?

Oh yeah, I forgot about the moons, thanks. They are supposed to be in that as well. It is a joke since Step 1 is impossible and the time constraints of everything is also impossible.

If we tried to do colonize now, this image shows the culture we'd have in 3 generations.

My high school math teacher. Unlike the teachers I had in primary school, he actually liked being a teacher. He made several million dollars in the dot-com boom, and retired at age 36. Went to George Peabody college, and then returned to his dumpy, bumfuck hometown to teach ignorant and unappreciative fucks like me. Died a few years ago, before I could return to tell him of how much I changed, and how I was going to make it. I think of him everyday.
