I'm a math major and I find that I can't concentrate without fast paced music, is there something wrong with me? I tried to quit but it's so hard.

Anon... help me...

What kind of music exactly? Examples?

because music provides dopamine and makes it less boring. if you can't concentrate without music its possible that you aren't interested in math and just deluding yourself

Is stress quantifiable? Can it be measured in any REAL way? Or is it relative/subjective? I keep coming across disingenuous shit like this:

>Measuring blood pressure and levels of inflammation are two physical examples of assessing stress.
>Stress already has been quantified. Probably the most famous, validated stress test of all time is the Social Readjustment Rating Scale, created in the 1960’s by psychologists, Thomas Holmes and Richard Rahe. They attempted to QUANTIFY all the major stressful events that might occur in a person’s life. They decided that the death of a spouse was the most difficult thing that a person could go through in life so they arbitrarily gave this event the value of 100 and worked down from there.

It's both. There are physiological markers as you say, including cortisol levels, and there is the individual's response to the physiological changes.

As genetic manipulation becomes more and more advanced, are we going to see biological machines replacing electrical ones?

Pic related is a mosquito fish. It's extremely small, eats planktons, constantly moves. Lives for about a year, doesn't grow into more than an inch or two.

Can you imagine creating a constantly moving machine at that size powered by a lithium battery? The machines that we have now are quite inefficient compared to biological systems.

Fuck no.
>>The machines that we have now are quite inefficient compared to biological systems.
not true, fucking shitter. Motors are 90% efficient, muscles are 30% efficient.

Not to mention we have not a goddamn clue how to engineer biological machines and won't for long time.

>>9088825
"Biological machines" are already used to produce various chemicals. The typical example are bacteria that produce proteins that are great for snowmaking. I would think that the pharmaceutical industry uses bacteria everywhere.

For energy and motion, biological materials are not very good. As stated earlier, electric motors have much better efficiency than muscles. Energy conversion is also more efficient with electronics, but biological power plants (no pun intended) are obviously cheaper to manufacture.

Information processing is debatable, as it seems that human brains will still be the top dog for quite a while. Still, transistors are much more efficient with energy and space, so they are in a sense superior. However, designing computers similar to a brain is not doable with current technology, and nerve cells do have other nice functions that would require multiple transistors to reproduce.

All in all, electrical machines are almost always more efficient, but biological machines are mostly readily designed and often cheaper to produce.

Yes, but when you put either them together with a skeletal system and control system, biological still has a huge edge. Control systems for robotic movement such as bipedal gait, and fine motor control of for example hand and finger movement, are in their infancy.

Are we more intelligent than our parents and grandparents thanks to the internet?

Because thanks to the internet we have a free access to almost all the knowledges of the world.

Knowledge doesn't equal intelligence. If you don't know what to do with your knowledge it's rather worthless.

Does Cigarette smoke fuck up your electronics or is it just a meme?

According to /g/ it does.

I'm pretty sure it is because of the ashes that you blow away when you smoke, so when this smoke gets into some electronics, it fuck ups everything and especially on the ones that need a fan in order to function.

In the context of pursuing greater intelligence, may I report to you for your edification that the active chemicals in cigarette smoke stunt the process of neurogenesis amongst other important neuronal health functions in the hippocampus specifically though likely not exclusively.

Ergo, if the electronics your question is referring to are of the electrical signals interplaying between your brains dendrites and synaptic pathways, yes. Yes cigarettes are bad, mkay?

(pictures relation undetermined)

>>9088736
It causes a mess of smoke and ash, so I imagine it can fuck with some electronics, especially those exposed, yes.

I have a proficiency test for Calculus 1 in 2 weeks. It will be the first academic related thing I've done in college ever.

I remember in middle school being shown a video of a probe crash landing on a gas giant that was previously thought of as not having a surface. Does anyone else recall the same video? I'm trying to find out what planet that was because I find it entirely just amazing that someone wasted all that time sending a probe to this planet, found out it has a surface, then watching as their probe fell to the ground and broke.

You're probably thinking of Titan, which is a moon of Saturn
>>
>>9088704
But the probe on Titan didn't crash land.
OP is probably thinking of Venus.

>that someone wasted all that time sending a probe to this planet, found out it has a surface, then watching as their probe fell to the ground and broke.
You remember incorrectly. It was Venus and nobody thought Venus was a gas giant. The probe didn't fell and broke, it stopped working because of the extreme conditions on the surface. And I don't think there is even a video, all I've seen were pictures. Unless what you saw was fictional or some kind of simulation in which case I can't help you.

I have a Math test tomorrow on Probability, Counting techniques (combinatorics/permutations etc), Indices and Exponential equations/functions.
How can these topics be combined for test type questions given there is a calc free and calc assumed section?

No, as far as I know his contributions to mathematics were minute which means that he was merely an outstanding brainlet.

Yes because he didn't feel any emotions.

So, /sci. What is your opinion on alchemy? I've only very recently (I'm talking past couple of weeks) gotten into basic research of it. I'm sure a lot of you have seen the video of the Russian man who made a Homunculus? He crossed a chicken egg and his own sperm and created some pretty bizarre creatures. What are your thoughts?
