Yes and no, depends on the person. I know a few bio majors who are like what you described. However a friend of mine has been top of the class and he studies like a champ. 5-7 hour sessions of reviewing notes, re-watching lectures, and re-reading textbook chapters over and over.

If you aren't naturally gifted then you get out what you put in. If you do shit all study expect shit grades.

Congratiulations, 'murrica!

Recently a so called "superbug" was found. This is a bacteria resistant to the antimicrobial drugs typically used to kill them, each year about 700,000 die from superbugs.

Why are superbugs a thing? Because there are more and more antibiotic agents each year. Say thanks to factory farming, say thanks to industrial farming where it's all about profit.

Basically with every new stuff we spray on them we exponentially speed up their evolution.


And now we face the challenges of a future where a simple...

The solution is really, really simple:

Mix multiple antibiotics together so that bacteria can't simultaneously evolve resistance to all of them. Crisis averted.

Also it doesn't make sense to stop prescribing antibiotics because you're afraid that the antibiotics you're not allowed to use might lose effectiveness.

Go to any local doctors office or hospital. There will be at least one infographic directed at patients or doctors urging the sparing use of broad-spectrum antibiotics. The Healthcare community recognizes the risk and is working to slow it with targeted antibiotics, for instance.

>Mix multiple antibiotics together so that bacteria can't simultaneously evolve resistance to all of them. Crisis averted.

Hahaha, no.
That's exactly what they do.
That's exactly why the crisis is coming.


Also nobody said we shouldn't use antibiotics at all. It's about the many places where antibiotics could easily be avoided.
Multiresistant bacteria are not caused by antibiotics, but by the excessive use of them.

Do you think that psychopathy is linked with nature or nurture?

I do not believe that something so prevalent and well documented over hundreds of years could result from a (nearly even) combination of the two since differences between cultures, standards within individual cultures, quality of life, and parenting styles are always different and constantly changing.

You can have a genetic predisposition to psychopathy, but experiences during development can trigger a break with reality. There are cultural differences, of course. Look up rates of schizophrenia in first and third world countries. Yes its both.

To all the dumb physicists in here trying to give ontological character to their mathematical discourse (which is only descriptive of relational properties):

"But hitherto I have not been able to discover the cause of those properties of gravity from phænomena, and I frame no hypotheses. For whatever is not deduc’d from the phænomena, is to be called an hypothesis; and hypotheses, whether metaphysical or physical, whether of occult qualities or mechanical, have no place in experimental philosophy." -Isaac Newton

So I made a hypothetical planet called "Cerza" which I think would be just great for life, try and find any flaws in it.

Cerza is a water planet with an average global temperature of 500 degrees Celsius, so I guess steam planet is better. It's 2 times larger than Earth and its atmosphere of water vapor is 10 time denser. Its home star is the same size as ours so to achieve its heat it would be about 3 times closer to its star than ours. The dense atmosphere would act as a sort of buffed up ozone layer for the planet, defending it from harmful radiation...

What would be some modern theoretical applications of a gravitational canceler, being reproduced like Ed Leedskalnin created? He used it to move giant stones and balance them on their center of gravity, such as a four-ton door that was destroyed in the 80's when scientists tried to study it.

In one of his Readings, Edgar Cayce, when asked how the broken axehead floated in the story of Elijah, said that the building blocks for the Pyramid of Giza, were lifted up by the same power. He said that we would discover the secret in the year '68, but since Leedskalnin...

If we take b=0, a = -1, and c = some positive number, then your question translates to
"if (-1)*x^2 + (0)*x + c = 0, and if x = ((-(0)+((0)^2-4(-1)c)^(1/2))/2(-1)) or ((-(0) - ((0)^2-4(-1)c)^(1/2))/2(-1)) , then shouldn't ((-(0)+((0)^2-4(-1)c)^(1/2))/2(-1)) = ((-(0) - ((0)^2-4(-1)c)^(1/2))/2(-1)) be true? No, if x is this number, OR that number, it does not mean it is this number AND that number.

What exactly happens in your body when you reach your breaking point?

How does mental and physical exhaustion differ?

And how can you know what your true and imagined breaking point is?

Examples: when I am running and feel the urge to stop but keep going on until I feel like I just have to stop. Was this my phyiscal or psychological breaking point or was it neither? Could I still have went on for longer? What prevented me from it?

Similarly when studying and I just feel too tired to focus. What exactly is it that prevents me to study for another...

pratice helps build endurance in almost all things. To answer your question it's a bit of both it's a safety guard/device in your mind and body to not over exhaust anything. Just listen to it and don't push yourself to hard you will probably won't amount to anything anyway.

34 KB,
I'm not at all sure if this question is too asinine or not, but I wanted to ask /sci/ about the relative pro's or cons of transport by pipeline as opposed to transport by rail or road or other vehicle.

Whenever a resource is available as a fluid, it's generally transported through pipes. We rarely see companies extract oil from the ground and then truck it from place to place. Similarly with water, it's delivered via pipe, as it's cheaper.

So I'm wondering, say we fluidised the worlds largest traded solid resources, i.e., convert...

The biggest (of many) problems with this approach is that melting say, iron takes a fuckton of energy. And you have to heat the entire length of the pipe enough to _keep_ the iron liquid, or else it's just going to solidify a mile down the pipeline.

>>8101087
The post mentioned that resources like iron would be fluidised by conversion to an aqueous salt like a sulfate or nitrate, and then transported by being dissolved in water. No molten metal needed; I'm thinking more of an add on to existing water distribution networks with a system of refining out the bulk goods before the waters use for drinking or agricultural purposes. Perhaps I should have been clearer on this point.

>how would a theoretical, untested and unproven method of transportation for goods, which doesn't even yield results in google, fare against the established methods of transportation of goods, for which actual data exists
if you want a clear answer:
how the hell are we supposed to know

if you want an uneducated, speculative answer based on nothing but vague assumptions:
maybe
