I have not been in a lab for a while, but I disapprove of your dirty beaker. Go give it a nice steam bath.

Yikes! Well, I hope whomever did that at least made some nice bling.

Ok /sci/, I was reading a book on Antarctic meteorites and they mention an element discovered in a meteorite in Antarctica with the abbreviation of Fb, I looked it up online and couldn't find shit and it isn't mentioned anywhere else in the book. Now I'm dying to know can someone please let me in on any information they have? I've been searching for hours and have no luck so far.

Thanks!

Just got reminded about the dihydrogen monoxide thing and am wondering why the prefix is 'di' instead of 'bi'.

Can anyone explain our point me in the right direction to find out?

Can someone help explain the relationship between qubits and the many worlds interpretation?

Is DWave a quantum computer? Have any of the subunits been proven to use qubits? Is that evidence of a parallel universe?

>>
>>8615137

Well, that was part of my question.

Even though I took quantum physics, I don't know near enough to interpret almost any of the articles discussing quantum computers.

I heard a description (I think the CEO of DWave) which suggested that qubits are somehow borrowing compute power from a different dimension.

That sounds like non-sense to me, but they supposedly are using that interpretation to build an implementation of a quantum computer.

Or do you think DWave isn't really a quantum computer and that description is bunk?

What do you think about this English major's show /sci/? What would you have done differently in that isolation chamber? Is he a weak brainlet for opening that door?

Medfags report in

28 y/o woman with familial history of arterial hypertension (father) & persistent headache, arterial blood pressure was 220/130mmHg and stays over 180/110 despite a two week anti-hypertensive therapy, dipstick urinalysis was positive for proteins and negative for leukocytes, erythrocytes and nitrates. Endocrinologist said everything is normal, she was referred back to me with the diagnosis of essential hypertension, do you agree with this diagnosis?

>>8613753
when your life accomplishments are being a fat shit, ripping off another person's video game concept to badly design and program a video game that luckily became very popular giving you lots of money, you use that money for all sorts of things normal people use money for. But then when you have everything arleady, you realise that you are a fat shit that has contributed nothing to the world, you are going to die alone because you have no family, all your friends have a price tag, and you have left no conceivable achievements that further the growth and wellbeing of humanity (instead, you have spawned a creation that has addicted millions of young children, now under the sedation of microsoft and google). You realise this, sitting among all your hookers, fake money-friends and billion dollar house that despite all that you have, you are still a fat shit and no one cares about you. It is therefore understandable that the man in that pic is bored and miserable

Bored people are boring people. Happiness is something one has go pursue on its own right. It rarely comes to people willingly.

Is this possible? Say there are infinite monkeys with infinite typewriters for infinite time. Would one of them eventually produce Hamlet by Shakespeare?

Hi /sci/, 2nd year student in chemical engineering here.
I'm doing a internship in a malthouse and I need to do a modelization of the kilning process, where the germinated barley is dried to produce malt. The goal here is to predict the final humidity of the malt for different temperatures, durations and air recirculations percents (using matlab/python).
I never done this before so I'm a little confused right now. Anyone has any ideas or tips of where I should start?

Also a 2nd year ChemE student, and you have my dream position. Any tips/warnings for getting into the industry? If you dont mind me asking, whos your employer?
>>
>>8607927
Try doing some home brewing so you can start understanding the industry, got my job by giving the interviewer a beer I had made myself. The processus is mainly biochemistry, so I hope you like biology/biochem. However, chemE is also very useful as transport phenomena and the likes will help you optimise the different processus.
Sorry but I don't like to post personal infoon 4chan so I can't say who I work for.

Watching that video yesterday made me very hopeful for the future of mathematics. In the past I have doubted if we can really do mathematics without reals but this just does it. This is how you replace reals with rationals.

And think about it for a second. Real numbers are defined as cauchy sequences of rational numbers (or as cuts which are very similar) but then through logic we can prove that basically lines are perfectly continuous and that means we have to be less rigorous in the future. We can simply call a number "root 2" and we know it is there.

Wildberger is making this more rigorous. Instead of making a set of cauchy sequences (reals), what he is asking is that in any problem you literally prove that such a sequence exist.

Think about it. You have a never ending family of [math] w_1 , w_2 , ... w_i , ... [/math] rational numbers. That never ending family is a cauchy sequence! And then [math] p ( w_i ) [/math] is a cauchy sequence which convergence to 0.

Wildberger did it! In the past cauchy sequences were a brainlet tool to make problems easier and that is where the problem with reals come from. When you say "lol there are just reals everywhere, don't worry about it ;^)" then you ignore a lot of the complications with real numbers but here Wildberger is very explicit. To solve a polynomial with a real root you must literally find the cauchy sequence and be very explicit about it and its quadrance.

It is simply amazing. I now definitely think this man can rewrite analysis in terms of rational numbers. It is amazing.

in my experience there are three types of people with regards to understanding philosphy.

1) Average joe, never thinks about anything, thinks that philosophy is a waste of time.

2) Above average intelligence, loves intellectualism, thinks philosophy is good because it has a historical status of being intellectual.

3) Actually smart, naturally engages in philosophical thinking, and acknowledges that it is completely valueless, unprovable, time-consuming mental masturbation.

Is this right?

>>8602324
Yes, gifted people are more aware about the limits and uses of philosophy, and that it is more about enjoying thinking rather than the utilities it provides
But none of the gifted people I met considered it useless or time consuming, they actually loved philosophical discussions without an exception
