Could a magnetic monopole be created during a supernova?
My calculations (though shitty estimates) show more than enough energy would be released.
they don't exist
string theory is a meme
gladiator sucked
engineering is basically just like accounting

This meme is related to gladiator?

Is this /sci/ approved?

It's good for normal people who are curious about basic scientific concepts and interesting anecdotes. It's not very suited to the flat earthers and moon landing deniers who infest this board, though.
I thought it was great
On November 2nd, 2019, a letter arrived at the office of the president of the united states.
It read, "On November 4th, 2019, the Washington monument will disappear. In two years, the entirety of the Hawaiian islands will vanish in a similar fashion."
After a brief panic about a terror attack on the monument, security swept the area, found nothing, heightened surveillance, and sent a few more guards out to make sure no one was doing anything suspicious near it.
On the 4th, the security teams observed the monument throughout the day, and closed it to tourists.
At 2:32 PM, it vanished instantly.
The rush of air to fill the vacuum left by it ripped a couple of the surrounding american flags off their poles, and for anyone within 20 meters, their ears had a good pop as they were pulled slightly towards it by a gust of negative pressure. Two guards were inside the building, performing a tertiary sweep for explosives. They vanished along with it.
The US government now had a two year countdown until Hawaii disappeared.
Alright, /sci/, this is where y'all come in.
What would be the scientific ramifications of this happening, what steps would be taken, who would be involved, what would the end result be?
I don't see enough fun threads on /sci/
You guys are no fun
Y'know this could be an interesting thread if you guys just spent like 30 seconds to read it

At least you got dubs
So I wonder if there is scientific evidence that excessive masturbation and porn use is negative?
After hearing a lot of stories on nofap I got curious and tried it. Have been nofap/noporn for the past 3 weeks and honestly it feels amazing and will continue with it. But I also believe if it may possibly be placebo.
One of the few studies I've found show that on the 7th day of nofap testosterone in men is increased to 150% and then levels out after that:
http://www.ncbi.nlm.nih.gov/pubmed/12659241
There was another study that says it takes 3 days after masturbating for your testosterone level to go back up to it's normal levels. So if you masturbate every 2 days, your testosterone will be lower than normal.
Anyone have opinions / thoughts / studies / experiences on this subject?

go/weiqi/baduk vs chess
which one?
>>7841922
Chess because it sounds the least african out of all choices.
I'll vote for go
go is a 3000 year old game originating in China
Hey /sci/, I almost asked this in /g/ but thought I would be better off here.
What calculator is overal a good one to own? I need a new one. is the ti 84 overrated or is there a better one for the money? or is it a thing to just accept and not be too autistic about?
>>7841898
Ti-84 is a meme. Just grab any scientific calculator and you're set.
>>7841900
So what is a /sci/ approved calculator?
>>7841900
Yes and no. Casios are generally inferior to the TI 8X series, and my scientific basis for that statement is that any time I play with a Casio, I just plain don't like the layout relative to the previously mentioned calculators.
I've played with 83s, 86s and 89s. They're fun for games and HS-tier stuff, and can even be used for arithmetic. Talking about the various functions of TI calculators is a total anachronism these days though, what with the much more powerful computers/calculators everyone carries around in their pockets.
If you really want a stand-alone calculator, I would recommend one of the above (since you're going to drop a chunk of change anyway), depending on what you want. I seem to remember playing with an 84 maybe once or twice and not liking it, like it was unnecessary increment in functions between the 83 and 86. Either way if you do math above linear algebra your calculator will be of no help, and for the stuff below, you will probably have to sit at least one test at some point without a calculator - they have to check whether you've internalized the ideas, after all.
All I used calculators for now is arithmetic and some double-checks with series manipulation. Even just opening up an Excel sheet is usually faster and easier to read.
If exoplanets discovered by scientists are what they were thousands of (light) years ago what if life developed on them thousands of years later in our present time? Theres no way to confirm the existence of alien life because you're always looking back thousands of years into the past with the telescopes!

>life developed
>thousands of years
More like millions/billions
The most distant individual star visible to the unaided eye is a little over 4000 light years away
>>7841895
Well, actually observing the ariens isn't the only way of confirming their existence, we could also pick up on waves, if any ever come our way, which is super unlikely.

Degrees don't matter anymore. Find a sector of personal interest, then write a useful lib and provide support. This is the only CV that matters in CS.

Most CS majors can't actually code for shit beyond their lecture notes.
Why is the UK so shit?
STE in STEM has unemployment of at least 8% across the board. And those salaries seem really crappy considering the £40k+ student debts.
Is the heat death of the universe theoretically survivable?
I'm arguing with my jackass brother, he says that as long as an inhabited planet produces enough heat and energy, that it can sustain itself through the nearly absolute-zero temperature of the rest of the universe.
Fucking what
Your brother is retarded.
.....and where would this energy come from, that wouldn't eventually run out?

He is right.

You just missed the smartest guy alive thread. He would have been the king
>>7843142
No one thinks he's the smartest guy alive. He's just a mathematician who disagrees with the current dogma about the foundations of mathematics, and he has plenty of great mathematicians on his side.
Alright guys, help me out.
Big bang was caused by matter and antimatter moving to each other slowly creating a dense world structure that created a huge release of energy.
I can be wrong I'm not a scientist. Correct me if I'm wrong. The question relates to what happened before big bang.
Now my question is, how was the matter created in the first place? Where did it come from?
>>7841685
It came from the past universe.
Our universe is just repeating itself infinitely. Expand, collapse, expand, collapse.

How to find the two graphs for which the distance between two of their points is 2 when the line joining those points is angled so that the angle is pi/2 at 0 and linearly approaches 0 when approaching c, and the same applies symmetrically when approaching -c?
The graphs only need to have this property in (-c-1, c+1)

if one dimensional objects have length,
two dimensional objects have area,
three dimensional objects have volume
what do four dimensional objects have?
or higher dimensional ones?
what do zero dimensional objects have?
n-dimensional volume, it really is just a name
We just say 4-dimensional volume, 5-dimensional volume, etc.
A zero dimensional object has no analogous value, so there is no word for it.
