Wow, sounds like "one size fits all" to me. What a dismal world.
Some kids do great with books and classroom materials. Others of us excelled with a rapid flurry of hands-on programming and lab exercises, with healthy doses of welding, machining, soldering, and troubleshooting.
This sounds like a dismal future for public school, and a bright opportunity for private & charter schools.
NASA doesn't control what SpaceX flies, unless NASA owns the cargo. SpaceX can re-fly whatever they want, as long as their customer (assuming there is one) is willing to accept the risk.
It would be very amusing if the recovered first stage were brought back to Texas and used to chase around and herd cattle.
With that said, I don't think SpaceX is here to amuse anyone. The graft and collusion between ULA and the USAF might have irritated SpaceX into being slightly more productively aggressive.
Nations are never great. Societies and cultures that choose to be free - free to think, free to choose, free to express, free to travel and study anything - are what history has shown to be great.
Any country that allows it's people to be truly free will eventually be great, and will be remembered as great. Sometimes people forget who and why a group of people came to be known as great, but as we forget and repeat history, we will re-learn.
Aesop's fables, Damascus steel - two things that firmly point to cultural exchange between India and Mediterranean & Mesopotamian lands. Saying the Suryas draw from Mesopotamian sources in light of other historical evidence lends credibility to that assertion.
An Indian website hosts an article about an Indian mathematician who asks, "Did India discover Pythagoras theorem? A top mathematician answers" Gee, I wonder what his conclusion will be?
It seems the cradle of western civilization isn't close enough to India's back yard for most Indian's tastes. Given the opportunity, they'd re-write history. Anti-American sentiment, along with anti-western sentiment, runs deep, and maybe for good reason. But whatever that reason, Indian's perpetual desire to re-write history ad nauseam is growing a bit old. What next, an article about how an Indian, not a Greek documented and used calculus in the 3rd century BC, long before Newton?
It would be delightful if India could point to an original Indian version of Euclid's Elements, the oldest continuously used textbook in history. Such books shape minds for, well, eons, by teaching logical & rational thought. Seemed to work well for Abraham Lincoln, he carried around a copy in his saddle bag and studied it while traveling.
Instead of self-glorifying episodic re-writes, how about discussing continuous, progressive and well reasoned contributions to culture and civilization?
An aircraft can be equipped with any manner of cameras, sensors and antennas and still be operated as a non-commercial flight.
What is more interesting is the manner in which this equipment is added to an aircraft. Modifying an aircraft without some engineering oversight is generally a bad idea - people die from the unintended consequences of things coming lose, falling off, or by simply being a distraction in the cockpit.
Even 'experimental' aircraft must go through a well defined FAA certification program to make sure reasonable safety precautions are taken. Expect the same for drones that fly beyond visible range of the operator and that mix with other aircraft, manned or unmanned.
This list is my stab at things that might be essential to keep drones and airplanes from crashing into each other by allowing safe separation and accurate position reporting. If it's ridiculous, then please come up with a better list.
Of note, I did exclude an image sensor, which all manned aircraft currently have in the form of Mark I eyeballs. Perhaps drones should include a vision system of some kind as well.
I failed to address lots of specifics - specifics which need to be addressed to keep from risking lives.
Crop dusters fly around at low altitudes all over this country, as do many other GA and commercial aircraft, and they are all within their legal right to do so. A few weeks ago I encountered a couple of NASA aircraft operating around 200 AGL while taking air samples. One of those aircraft was a P3 Orion.
Few people realize what a complex task it is to integrate into the nations existing aviation infrastructure. It is a complex engineered system and it needs to be dealt with carefully.
Lose a friend or a family member in an airplane crash and you'll be a dick too.
The point isn't to 'own' the skies - it's to share as broadly and as safely as possible.
Just because you can afford to buy or operate some new tech toy doesn't mean you automatically have the right to go barging in to a complex engineered system without training and some reasonable adherence to regulations.
As for being a licensed drone pilot being a different class - agreed. Vertigo isn't likely to be a factor!
Ideally there would be 'drone recovery areas' where an autopilot would fly to automatically in the event of lost communications. There are lots of little details like this to work out. The big unanswered questions are those dealing with how to integrate safely with existing traffic. I'm not at all convinced that the FAA has a clear answer.
I have no concern for greasing bureaucrats palms - my concern is for my own life and the lives of those I share the skies with - as both a passenger and a pilot.
I've invested heavily in my flight training and I take the safety of myself, my passengers, and those I share the sky with very seriously.
Drone operators will take the safety of the entire aviation system seriously as well - either by will or by enforced regulation.
At the minimum, these are the requirements for somewhat safe integration into the existing airspace. Anything less is asking for big troubles for any private and commercial air traffic that shares the sky with these things:
1. Mode S Transponder 2. ADSB In & Out 3. Traffic Collision Avoidance System (TCAS) 4. May only operate in areas with active radar coverage under IFR flight plan (some legal airplanes do not have a transponder!) 4. Operators must be in constant contact and control of the drone and must be licensed pilots 5. altitude & airspace restrictions ( right of way: licensed drone rotorcraft fixed-wing airship )
Otherwise, they can keep below 300 AGL and in line of sight with their operators.
Anything less and drones will be a threat to anyone that flies on any airplane, anywhere.
The only role model that such a young girl needs are her parents. Be the change you want to see in the world.
Read stories to her that paint women in a different light. Here are some suggestions:
1. The story of Gorgo, queen of Sparta and wife of Leonidas. Gorgo was probably the first documented woman cryptanalyst in the history of western civilization. Reference: Codebreakers.
2. A beautiful and educated woman named Hedy Lamarr invented spread-spectrum technology. We can thank her for modern wifi and cell phones. Reference: Spread Spectrum: Hedy Lamarr and the mobile phone
Read to her. Daily. Schedule at least 6 hours per week.
Limit her exposure to television. When she does watch television, explain to her that much of what is on television is sexist, unenlightened and designed to extract money from the mindless consumer masses. Be thankful that as a girl she isn't likely to descent into the life-sucking hell of video games, but limit (eliminate?) exposure to gaming anyway, for everyone in your house, parents and kids alike. Children cannot grow and flourish if a majority of their free time is spent manipulating pixels in synthetic worlds.
Have her choose a musical instrument. Buy a quality instrument that produces nice sounds. Hire a tutor. Take lessons with her if you don't already play an instrument.
As she gets a little older, buy educational toys for her, such as an electronics kit. You'll probably have to play with her yourself with such toys as other kids her age might not be interested.
see muon-catalyzed fusion (Wikipedia). This is a very real example of peer-reviewed and repeatable cold-fusion. Is this the only way to overcome the coulomb barrier and accomplish cold-fusion? Probably not...
The astronauts' physiological vital signs were being monitored back on Earth, and the Flight surgeons noticed some irregularities in Irwin's heart rhythms.[9] Irwin's heart had developed bigeminy.[10] Dr. Charles Berry stated to Chris Kraft, deputy director of the Manned Spacecraft Center (MSC) at the time: "It's serious, [i]f he were on Earth. I'd have him in ICU being treated for a heart attack."[10] Endeavour's cabin atmosphere was 100% oxygen when in space, so it was decided that he was in no serious danger by Dr. Charles Berry.[10] Specifically, "In truth,...he's in an ICU. He's getting one hundred percent oxygen, he's being continuously monitored, and best of all, he's in zero g. Whatever strain his heart is under, well, we can't do better than zero g."
A hydrogen economy is so far off that it's even more fiction than a Tesla. There are at least two Tesla dealerships in the Denver, Colorado area, and these cars are in fact driving around (at least the Roadsters).
First, hydrogen is just an energy carrier. How are you going to produce this hydrogen?
Second, once you produce hydrogen, how are you going to distribute it around? Replace natural gas? Not for hundreds of years....
If you have the energy to produce hydrogen, why not just use the existing grid? Sure, the US electrical grid needs some TLC, but it is quite functional and is capable of serving a significant number of electric vehicles, especially when charged during off-peak hours. We have no infrastructure to produce and distribute hydrogen on any usable scale.
Money and greed indeed. If it wasn't MLK's family conflict, it would be something else. The point is that copyright is flawed, which just accentuates human flaws.
Instead of serving to distribute the literature and humanity that was MLK, copyright is being used for greed. This is sad, but no big surprise.
Fix copyright and patent laws to protect the individuals that originated the work, and the vultures less. Individuals who are able to create and inspire will continue to do so, and vultures will have to search a little harder for their financial carrion.
I find it disturbing that you critique LOTR the way you have, yet admit you've not read them. My 10 year old children have read and loved both the Hobbit and LOTR.
Tolkien's prose does assume a higher level of reading comprehension than is common today, this is very clear. Compare any Tolkien to JK Rowling. She tells nice stories, but with such stark simplicity that I find them painfully droll.
Woa, this is a new idea for me. I'm not an economist, just a lowly engineer, but I find this idea rather tickly in my brain. Do you have any books or references where this idea is investigated further?
Slashdot Mirror
So, the scumbag CEO Martin Shkreli responds to pressure.
Perhaps it's time to start pressuring this scumbag to stop wasting oxygen that someone else, certainly anyone else, deserve more.

Please stop killing people in the name of justice. Just stop.
The only ones on the list that have any factual basis:
1. Major asteroid impact
2. Super volcano
3. Ecological catastrophe
The others in the list seem to be the result fanciful imaginations or anti-science fear mongering. So, I'd like to add two more item to the list:
4. Failure to understand history/philosophy/science (aversion to rational thought)
5. Poisoned minds, poisoned cultures
Nations are never great. Societies and cultures that choose to be free - free to think, free to choose, free to express, free to travel and study anything - are what history has shown to be great.

This wording from his bio makes me think he hasn't quite learned his lesson:
"Today, he is actively pursuing various avenues in order to make full restitution to his alleged victims."

Tolkein's granddaughter read The Hobbit and gave it a nice review. I believe she was 13 at the time.
