/sci/ - Science & Math

I read this whole instruction manual on how to calibrate it and stuff, and it ends up being like twenty pages long. I read it slowly and carefully to make sure I remember everything and will be able to do my job tomorrow.

So this morning, I head to the lab to meet my professor, who asks me if I read what I was supposed to and will know what to do, to which I respond yes. Despite the twenty pages of reading, the procedure was actually pretty simple (or so it seemed).

I was led into the adjacent room, which was dimly lit. The walls were all concrete (cheap material with good halving thickness in case things go wrong) and the building itself just felt musty. He sat me down in front of a machine saying, "I'll be in the next room if you need any help."

I switched the thing on, and was greeted by a constant humming noise after a few seconds. So far so good. I first tuned the voltage to the correct setting, and everything still seemed peachy. Unfortunately, I failed to realize a small light on the back that was flashing to indicate an inconsistency with some of the frequency settings.

Had I read the CORRECT manual, I would have noticed the light (who puts an important light in the back, anyways?), and I would NOT have tried to tune the resistance next. Well I did, and I began to hear a quiet whining noise that started to grow louder. If anything, I could say that this sound was rare, but I thought, "Nahh, forget it. Yo Homes, to Bel-Air!" I pulled up to the house at bout seven or eight, I yelled to the cabbie 'Yo home, smell ya later!' I looked at my kingdom, I was finally there! To sit on my throne as the prince of Bel-Air!

Here is this week's rendition of Stupid Questions Thread: if it doesn't belong as its own topic, it's a stupid question.

To start off, this isn't homework, just stuff I'm working on on my own. I need help calculating the dynamic viscosity of Creatinine, whose molar mass is 113.12g/mol and specific heat is 1220.82J/kg/K. Creatinine has the molecular formula of C4H7N3O, and all the other tidbits that go with it.
I'm working with Ansys and applying different waste products to a bioreactor, but I'm having trouble with inputting this piece of information. The information can be either in Pa*s or kg/m/s.
Just a point in the right direction, not an answer, is sufficient.

I know it used to be big bang theory, but hasn't there been some problems with it recently? Isn't there like a black hole theory now?

What is the most credible theory for the creation of the universe or is there none that is credible?

>MUH PHYSICAL SCIENCES

Muh Sciences and muh mathematics!!

I masturbate to Michio kaku and Niel Degrasse-Tyson cause muh physics

If the sun is 93 million miles away and the speed of light is 860,000 mph, how come when I look up I immeditaly see the sun and it doesnt take like 2 minutes?

1. It wasn't big, the universe came from a singular point and expanded from it.
2. it was no bang, since there were no properties existing at that time to to make an explosion.

But other than that, Big Bang is a proven theory and everyone who deny's it should bring forth factual evidence to prove their argument.

I've been thinking over the past few days and one idea that came to mind is the idea that the big bang did create/recreate all of the known universe but it is still only a relatively small fraction of infinite time and space. Essentially, all matter that is in this portion of the universe was formed after the death of an ultra-massive black hole. This is similar to the big bang/big crunch theory of the universe. However, it didn't create anything. (Due to the nature of light we will never be able to see past the "beginning".) It just forced an unthinkable amount of matter into one point causing the energy to completely rip any matter down to an extremely basic state. And then once the black hole reached the absolute largest size it possibly could, BOOM! All of the basic matter is ejected out into space and everything is "rebuilt" by time. This next part makes the most sense to me. I personally hate the idea of dark energy as it shows how truly naive we are about the cosmos. Astrophysicists can't even explain exactly what it is. Based on this theory expansion is caused by matter filling in the void caused by the ultra-massive black hole. Remember, mass warps spacetime. An object that large would have had to seriously stretch the space around it. Eventually, the expansion would force the outlying areas of the universe to compress and collapse into ultra-massive black holes. Thus the big bang is just another cycle within a infinitely relative universe.

BTW. I have a pretty good understanding of mainstream theories of the universe. But I have no fucking clue how to to the math behind the theories. Personally, if I were to go back to school and pursue what I love, physics, particularly astrophysics and quantum mechanics, would be my major of choice.

Don't worry /x/, the rational arms of /sci/ will always be here to protect you!

Sup /sci/, I've got a mathematics and schooling question.
At the moment, I'm going to ITT Tech. I know it's not the best school but when I went in I didn't have many other options. Let's not harp on this.
Since I've started, I've completely fallen in love with math and I would much rather go farther in that rather than the cyber security degree I'm working towards right now. I did terribly in math in high school, but I've been getting straight A's in all classes including math since I've been back in school and I just finished trigonometry.
I know the credits wouldn't transfer, but would any university look at my math scores or my overall scores and offer some sort of scholarship? I've been on the perfect attendance, highest honors, and dean's list since I started.

bumping one last time

If the Big Bang theory says that the universe was already in a "extremely hot and dense state", then what created the universe, and that it is responsible for early development (not full creation), then what created the universe?

I'm trying to better understand the big bang theory

Does it mean the sudden expansion of all matter from a singularly? Or matter AND space?

Sure thing OP!

Let's imagine....

The universe was originally one massive blackhole. A blackhole is nothing more than a "quark star", similar to a neutron star where the gravity of the star has compressed the neutrons so close together that they have more or less become one enormous neutron.

As this "original" blackhole accretes most or all of the matter in the universe, it eventually reaches "ultimate density" at the core and explodes, similar to super novae.

This explosion is uneven and causes inequalities in the distribution and density of the exploding matter. Some of it remains close enough together that it remains condensed into blackholes while the rest expands into normal matter.

The normal matter that remains is attracted to these smaller blackholes and begins to accrete and build angular momentum as it falls toward them. The normal matter compresses into stars, and forms galaxies.

Discuss.

is there such a thing as absolute heat?

How do I make mad decent scores on the ACT?

I live in Mississippi, and the SAT is irrelevant here.

Does science explain HOW, or does it explain WHY?

If all the mass the universe is made of was once concentrated in one single "point"...do we, TODAY, all exist of these billions of years old atoms?

What i dont get...how does this work on a bigger level, like cell growth....birth of a child, for example. Are these atoms just rearranging to form a new "makro" body?

Am i made out of 13 billion years old atoms?

hey /sci/ I don't come here very often but how of curiosity , what is the scientific standard for how the universe started?
Is it still the big bang?
Or as modern science taken us farther?
