>Robots vs. Anesthesiologists
>Anesthesiologists, who are among the highest-paid physicians, have long fought people in health care who target their specialty to curb costs. Now the doctors are confronting a different kind of foe: machines.
>A new system called Sedasys, made by Johnson & Johnson, would automate the sedation of many patients undergoing colon-cancer screenings called colonoscopies. That could take anesthesiologists out of the room, eliminating a big source of income for the doctors. More than $1 billion is spent each year sedating patients undergoing otherwise painful colonoscopies, according to a RAND Corp. study that J&J sponsored.
>An anesthesiologist’s involvement typically adds $600 to $2,000 to the procedure’s cost, according to a research letter published online by JAMA Internal Medicine in July.
>By contrast, Sedasys would cost about $150 a procedure, according to people familiar with J&J’s pricing plans.

>Venture capitalist Vinod Khosla thinks the best way to improve health care is to get rid of most doctors.
>Human judgment simply cannot compete against machine-learning systems that derive predictions from millions of data points, Khosla told an audience Friday, the third and final day of Stanford University School of Medicine’s Big Data in Biomedicine Conference.
>But Khosla devoted his hour-long keynote speech Friday to his long-held belief that technology will replace 80 to 90 percent of doctors’ role in the decision-making process. His is one interpretation of the implications of big data — the popular term for the massive volumes of digital information generated by electronic health records, genetic sequencing, clinical trials and other sources.
>“I don’t agree with 80 percent of your remarks,” one clinician told him.
>Khosla acknowledged his view is often not a popular one, but did not back down.
>“Humans are not good when 500 variables affect a disease. We can handle three to five to seven, maybe,” he said. “We are guided too much by opinions, not by statistical science.”

So CS will basically eliminate the need for most of the MDs.

Fuck yes. I hate doctors so much.
>Just come to my office, we can fit you in next February. I'll have my secretary make a note so I can keep you waiting for two hours and then spend five minutes with you, glance at your chart while I half-listen to you and think about what I'm going to have for supper, then prescribe you some medicine that doesn't have anything to do with your problem and makes you impotent. My life is awesome since my powerful and respected professional organization opposes every effort to keep me from being the undersupplied bottleneck to your healthcare.
>>6557162
That's cute but no. They might replace nurse anesthetists though I guess but these complicated OR robots have abysmal track records. Just look at the de vinci for OB (and that's a robot controlled by a doctor, it looks like this thing doesn't even have that).

Sounds like you have some regrets in life.
This is a thread for the SpaceX unveiling of the new Dragon.
It will happen Thursday evening, more details (and streaming video) here:
http://www.spacex.com/webcast/
I'm posting early so people can hear about it and plan to watch it, and also for people to make guesses about what they'll reveal.
I'm going to go out on a limb and guess that they'll also be surprise-announcing their reusable upper stage, so in theory they can recover and reuse all three components of their crew launch system this year.
Dragon is an American reusable space capsule which currently is used to carry cargo to the ISS. It has always been intended to be developed into a crew vehicle.
The Dragon V2 is the crew-rated version. The main feature which needed to be added is the "launch abort system", or a powerful rocket which can be used to separate the capsule from the launch vehicle in case the launch vehicle starts to blow up or otherwise crash.
While Dragon V2 is capable of ocean splashdown (the recovery method used for the original Dragon), it is intended to land on solid ground, making it much safer and more pleasant for the passengers, and also more likely to return the capsule in good condition for reuse.
It's designed for three landing modes: parachute splashdown, parachute landing with rocket-assisted touchdown on land (which should be survivable if the rockets fail entirely, and a comfortable soft landing if the rocket works), and pure propulsive landing on land.
Many things are still unknown about the details of the V2. Elon Musk, the CEO and Chief Designer, has implied that there will be surprising changes to its appearance. It is being speculated that the V2 will be a trunk-integrated, trunkless, or trunk-optional design, for total reusability. The capsule would need extensive redesign if the trunk is integrated.
>>6560721
I intend to follow this on my usual channels.
I personally like the decision to use spaceX primarily for ISS missions so that Orion can focus on the deeper space exploration.
It's been a long time coming...
This is the design of the current Dragon.
The trunk, which does not return from orbit, is an important service module as well as providing additional cargo space. With its large solar array, it can provide power for very long stays in space. This will enable the "DragonLab" missions, in which the Dragon will be launched as a miniature self-contained space station for extended microgravity experiments of the type which would be performed on the ISS.
Making the Dragon V2 capable of launching and navigating to the ISS, or other space stations (such as proposed space hotels taking advantage of low priced launch services to provide adventurous millionaires with exotic vacations), without the trunk would enable a fully-reusable crew launch system, potentially reducing launch costs near the cost of the fuel, which is presently a small fraction of a percent of launching an expendable rocket.
Is it ever going to be worth it getting into this field or any of its subsets? Or is it a dead-end?
Thinking about two things: psychopharmacology, and consciousness uploading (and what it implies concerning VR and such).
>>6558384
Huh. Are there NO opportunities at all outside of pure research/teaching and publishing?
>>6558387
Oh there are. Pharmas are always pushing for new drugs. But who you know matters more than what you know.
The place for all stupid questions that don't deserve their own threads.
Continuing on from >>6513440
Is color an inherent property of matter? Or do certain objects just absorb/reflect different wavelengths of visible light? example, is a leaf green because it reflects green light but absorbs the other wavelengths?
Is there some law of physics which dictates the lower limit of the size of a particle, of could a particle theoretically be infinitely small?
You want to know how to learn something?
You want to know which textbook or videos or problem sets to use to learn something?
Post ITT.
I want:
First year mathematics (precalculus, differentiation, integration, linear algebra, complex)
First year physics (motion, thermodynamics. electromagnetism, light, semiconductors)
Java
>>6554507
I would prefer a textbook or video series that uses lots of diagrams, not big blocks of text
>>6554507
I would prefer straight theorems and examples with some additional problem sets
What do you think of this:
For maths - Stewart
For physics - Halliday OR Sears&Zemansky
Does this sound good?
Are you going to get cryonically preserved? Why or why not?
It's not that expensive. At the Cryonics Institute, you can have your full body preserved for about $30k. CI currently has over 100 humans preserved in liquid nitrogen in Michigan. Alcor has about the same amount.
https://en.wikipedia.org/wiki/Cryonics
No, I can't see a way of cells being destroyed via crystal formation ever being reversed. I also can't see the point of getting a few more years once my cells have degraded through ageing, it's not like they will be able to give me my 20yo body back.
I see Cryonics as nothing more than offering hope of life after death to the non-religious.
>>6564509
What if you're wrong though? You could be losing out on eternity. Suppose immortality and restoring cryonically frozen bodies is possible within the next thousand years.
Ray Kurzweil, the futurist most of you have probably heard of, is an Alcor member.
These are the tanks you would be stored in. They need to be filled with liquid nitrogen once in a while, but they don't use electricity.
>>6564524
If you think it has potential then drop the $30k, I'll spend it on having fun in this life.

It doesn't look like typical meteorite pics so I'm asking for advice. One guy in the last thread (on /b/, I wrongly assumed some experts still /b/rowsed) posted a meteorite pic that looked strikingly similar to the shape as well as surface texture.
I don't have any magnets but some stuff clung on to my tweezers when I tried to sift through to show you guys big piece of what's fallen off.
This is the rock, the next pic will be some of the stuff that's fallen off onto what it was set on. I've taken this pic on standard printer paper for a size reference, it's 15lbs.
I even have a blurry video showing the stuff sticking to my tweezers if anyone can tell me how to make a webm.
>>6564410
Please refrain from commenting on here/hear typo in the OP. I apologize and am not realizing how out of it I currently feel.
Here's the "stuff", I'm currently showing how it surprisingly stuck to my tweezers, and if you note between this pic and the next the different in how much dark dust stuff is sticking to these little colored rocks I'm sure you can see that whatever this stuff is it's clearly magnetic.
>>6564417
Here's a pic I took of those few pieces earlier before I dumped more stuff that fell off onto the pile and realized all the little shavings were sticking to the colored rock pieces.
>>6564417
This was the wrong pic, pic related.
I feel that going into space is a wasteful and fruitless concept. There is no way we could gain anything with exception of them minerals in the spaces (which even then it would be nearly impossible). Interstellar travel isn't likely, and at no point will humans all band together to make some sort of "space empire". I don't see the use of space missions aside from researching zero G things.
Discuss, gentlemen.
I agree.
PhD here. I fully agree.
