Tell me about biology, is this a science ?

big pvalues for you

If I will take a PhD in Biology, will /sci/ die ?
>>8096897
It would be extremely unprofitable
Roughly, how much time would it take for us take some chimpanzees and through artifical selection make them as inteligent as humans?
long time
>>8096693
also, why aren't we doing it already?
>>8096709
Because chimpanzees are dicks, and you don't want smarter dicks.
So /sci/ what kind of work will the first few Astronauts once they land on Mars?
I know the main point will be to prove Humans being able to land / take off, but they'll still perform scientific work.
I'm thinking seismological experiments to try and get a better idea of the interior of Mars. Maybe also try and get geological samples to research the magnetism on Mars.
We currently and in the future have data have data from Rovers, but I'm assuming it's limited compared to what astronauts would be able to gather.
Any other ideas...

>> seismological experiments
Can be done (better) by robots
They will mostly hunt for rocks, plant flags, look good on TV, and leave.
Rovers are getting better. We might even be able to do the same stuff humans could do sans photo-ops with telerobots. You put humans in orbit around Mars and have them control robots on the surface. It makes doing a Mars mission a lot cheaper

I agree, I think they'd be doing a lot of geology and chemistry, as well as set up some seismometers. I think something else they should experiment with is biology, like testing how microbes act in the low gravity and low pressure environment. I have a feeling that because the intensity of the sun is less, the photosynthetic process may be effected. Maybe since it's less energy, plants wont produce as much sugar as we expect and this could cause trouble for civilization there. They should also experiment...

Looking for fossils would be the best/coolest/optimal thing human would do on mars better than robots imo. A matter of rock manipulation and visual recognition in situ than no explorer would do on its own.

Why do Americans shit where they eat?
What benefit is there to consistently dousing your lawn with chemicals for the soul purpose of aesthetics?
related: two of my neighbors across the street just had their lawns sprayed for weeds. Guy in huge truck pulls up with a huge tank and just starts spraying the lawn. I could smell it all the way into my yard.
Is there any specific scientific research to show how harmful weed control is to both the environment and human health?
>>8096585
Most often because home owner's association requires it.
Lawns are pretty bad though:

The U.S. Center for Disease Control and Prevention (CDC), in a study of 9,282 people nationwide, found pesticides in 100% of the people who had both blood and urine tested. The average person carried 13 of 23 pesticides tested. - See more at: http://learn.eartheasy.com/2009/01/lawn-care-chemicals-how-toxic-are-they/#sthash.pWfDyNZu.dpuf
Why are they still allowing the use of these practices then?
>>8096602
Why wouldn't we want pesticides in our blood and urine? I for one don't want any pests trying to crawl into my urethra, so I actively ingest pesticide on a daily basis.
Hey /sci. Undergrad here.
In my O-chem class, they taught us about meta, and ortho/para directors, and how they depend on being electron withdrawing/donating.
But what is the physical mechanism that forces the 2nd substituted group on the benzene into a the specific position? Any more experienced chemists here know?

Howdy /sci/, I have a quandary I was hoping you could help me solve. I have been having a discussion in a blacksmithing group on Facebook and I lack the knowledge to come up with a definitive answer. You see, we have been going back and forth on wether a specific style of tool called a shoulder-less hot cut will do significant damage to the anvil hardy hole either over time or in the short term. One side says it does no significant damage and the other says that eventually the tail will break off the anvil. The reason for the fear of a break is because of the taper on the shank...

Here is a picture of the tool in question for illustrative purposes.
Are you worried about damage to the anvil because of the lever action of the tool, or because of the wedging action possibly opening the hole wider than it used to be?
If the former, I can't imagine it would put any more stress on the anvil than normal use of that region would, and if the latter, I would imagine the hardened face would prevent hole enlargement quite well.
Those that don't like the pictured design are concerned the wedging action will split off the tail at the the hardy hole, most likely after years of use. I hold that most of the energy goes into dividing the hot steel and will not damage the anvil significantly. So I suppose opening the hole wider than it was is the concern and since it is a hardened steel face it shouldn't distort but instead crack and break. Not concerned about an levering here.
Does anyone else worry that the distance between human related science and technology grows bigger and bigger?
Our bodies remained pretty unchanged in all these years yet technology grows. We still don't understand how our brains work. We still can't cure a lot of illnesses and surgery is still is not complication free. But we fly to space, have self driving cars and high resolution displays that can be controlled by gestures.
Are medical fields neglected or are those simply more difficult and thus produce less and slower results? It should have top priority...

>le smartphones are the only new development meme
So you're retard #342214 who only sees smartphones so assume that's the pinnacle of human technology. How about you go compare cancer survival rates between 1970 and now?
>>8096347
way to strawman op. of course our medical tech is better than it ever was but it's developing slowly to what it could and should be. this is because of how industry is structured, a symptom of fucked up priorities. we have more people involved in developing bullshit apps than we have in medical research.

and don't get me started on all the biometric gimmicks like the fitbit and what not that soaks up bmes who should be working on actually useful things.
Why are scientists so bad with budgeting? In my experience (and I'm a postdoc at a top UK university) they get a grant then throw money at data generation with minimal planning until they've run out. I end up exasperated and spend lots of time trying to optimise how our funds are used in most of the projects I participate in.
Recently during a seminar one guy doing a presentation outlined his data generation strategy and another quipped "I know Anon will tell you that you've wasted half your budget" to general laughter of everyone present.

no, you're just working with mediocre people who have never been introduced to any management skills.

But I'm at a great institution and some of the people are among the most cited and well-known academics in their fields.
Where can I find the non-mediocre folks?

>But I'm at a great institution and some of the people are among the most cited and well-known academics in their fields.
doesn't mean anything. good people come from other institutions, not from your own.
>Where can I find the non-mediocre folks?
in a high-performing company I guess.

If multiverse theory is true
WHERE do these other universes exist, in relation to our universe?
Who is this vector erector semen demon ?
And the answer to your question is : No, there aren't mutliple universes.

For all you math majors, what's you're end goal once you get you're degree?
It's clear you can't all become math professors, so how does a degree in math earn you money once you graduate?

Why anon?
Have you talked to someone about it?
>>8096251
I've talked to many people about it, including several psychiatrists and psychotherapists. My life just isn't worth living. It's constant suffering. I'm just too intellectual for this world. I don't belong in this anti-intellectual society full or retards who will never understand me.
So when I was a little kid you could buy these crystal pack things where you put like water in a little dish then you had like a cardboard tree thing and it would somehow grow baby crystals right? Eventually I remember the tree got broken and I lost my baby crystals so they couldn't grow to be big proper crystals.
how then do they turn these baby crystals into crystals they want like emerald? Do they just add like food colouring and a the crystals turn green and that is a emerald? How long does it take to turn baby crystals into big proper crystals you can sell in...

You're not allowed to post these cool crystals informationals ever since that kid hospitalized himself on /b/.

the best hangover cure is not to drink
the second best cure is to drink as much water as you drink
if you think it's lame to drink water in between drinks, you're too immature to drink responsibly.
Drinking water is for sukers lol

What are some books you read that actually inspired you to pursue what you're doing today?
none
I find that something is truly yours when it arises within you without a lot of external influence, but because it makes you shiver or it makes you curious.
Only women and people who like to read like to get their ideas from others.

The way of the superior man
>>8096007
Dale Carnegie was passionate about human interaction and communication, he read every book on the subject and every biography of great leaders he could get his hands on.
Tesla was such an avid reader that he would memorize books and got up to a point where he even looked into HInduism texts for inspiration.
