Design: Generating Creative Ideos

David Kelley thinks everyone is creative, at least until the creativity is driven out. He teaches a course in creativity at Stanford University in the heart of the most famously creative city in the most creative industry in the most creative country. Peter Robinson interviews him on Uncommon Knowledge.
Kelley's 5 steps in the creative process (The video gives more detail at 12 minutes.)
  1. Empathize – bias for action: immerse yourself in the situation to be studied and see it from the typical user's perspective.
  2. Define – Explicitly define the problem to be solved, then iteratively re-define at as your project progresses.
  3. Ideate – with fluency and flexibility. Fluency says the way to have a good idea is to have lots of ideas and flexibility says make them different from one another. Find your ideas from talking to users and experts, looking at other ideas and at the state-of-the-art.
  4. Prototype – make something physical that lets people experience your idea.
  5. Test – Put your prototype in front of your ultimate judges and see what they think. Take their suggestions and make it better.

Why You Need to Understand Statistics

While this is "honest" in the sense of not being fraud, it is not honest in the sense of giving you the truth. If your skill in logic and statistics is weak, you will certainly walk away believing a falsehood. I'm not sure that is accidental.
More likely, it's a battle: an epic struggle between universities and student. You, to get their education and degree. They to get your money. Their side seems more sophisticated.

 Once upon a time, we marketed law schools with a printed brochure or two. That changed with the advent of the new century and the internet. Now marketing is pervasive: web pages, emails, blog posts, and forums.

With increased marketing, some educators began to worry about how we presented ourselves to students. As a sometime social scientist, I was particularly concerned about the way in which some law schools reported median salaries without disclosing the number of graduates supplying that information. A school could report that it had employment information from 99% of its graduates, that 60% were in private practice, and that the median salary for those private practitioners was $120,000. Nowhere did the reader learn that only 45% of the graduates reported salary information.

Smarter Every Day at the Motocross Track

There are some really good YouTube video sites. My favorite science channel must be Smarter Every Day. In 3-8 minutes, Destin finds some interesting thing to describe and investigate. His giddy enthusiasm, unfailing wonder and wholesome, humble southern demeanor make it awesome*.
(Having a $100,000 camera that shoots 250,000 frames per second doesn't hurt, either.)
Here is Destin investigating angular momentum at the motocross track.
*Destin-approved vocabulary

Having watched every video, here is my annotated list of Smarter Every Day episodes.

How is Work?

Have you heard of TED talks? Do you know people who won't shut up about TED talks. Well, you're right they can be overplayed and the moments of genius seem to be in decline. Even so, there are gems. Cringing awkward storytelling mixed with crisp insight: here is my favorite from six years ago.

If you want to know more about Mike Rowe and the state of work in North America, go here. For more stories, go here.

What's so bad about work, anyway? John Calvin got it right five hundred years ago. Work is only secondarily that stuff we do to put food on the table. “Follow your passions”, “Do what you love and the money will follow”: that's the third priority, at best. No, work is how we serve one another and a practical way to show love.

Are There Moral Facts?

Compare
Fact: Something that is true about a subject and can be tested or proven.
Opinion: What someone thinks, feels, or believes.
http://www.cartoonstock.com/directory/r/right_and_wrong.asp
With
-Copying homework assignments is wrong.
-Cursing in school is inappropriate behavior.
-All men are created equal.
One of them must be wrong.

Two Views of Intelligence

http://ronalvesteffer.com/5-ways-to-work-smart-not-hard/
Do you think you're a natural at science? ...math? ...English? Sorry to hear that.
The mastery-oriented children, on the other hand, think intelligence is malleable and can be developed through education and hard work. They want to learn above all else. After all, if you believe that you can expand your intellectual skills, you want to do just that. Because slipups stem from a lack of effort or acquirable skills, not fixed ability, they can be remedied by perseverance. Challenges are energizing rather than intimidating; they offer opportunities to learn. Students with such a growth mind-set, we predicted, were destined for greater academic success and were quite likely to outperform their counterparts.

The European Founding

(Formerly known as the "dark ages*" )
"We dismiss the achievements of our ancestors and fall short of them.They (the medievals) honored their ancestors and surpassed them" Anthony Esolen, 2015

*They were called "dark" because those who called themselves "the enlightenment" and their enthusiasts thought the dark ages were a time of ignorance, insularity and stagnation. The last 40 years of historical scholarship show that is not true. The remaining justification for calling them "dark" is that they are poorly recorded. They are poorly recorded because the enlightenment "scholars" destroyed their manuscripts.

Brain Research


http://teenagebrain.blogspot.ca/

Humans grow, various parts at various rates. The brain is most difficult. It starts biggest and finishes last, which means it is still in full development in the late teens when the body looks pretty much fully grown.

"I Don't Know How You'll Survive When Our Genes Are Gone."


http://favim.com/image/33772/
The epic scale of the lyrics to the Big Bang Theory is no accident. The whole show is  a metaphor for the creation of the human race from Cro-Magnon and Neanderthal. You see, recent research on the Neanderthal genome suggests interbreeding.

The genes for red hair and pale skin didn't match well enough to show a correlation, but I found a correlation for genes linked to other traits. There's a gene cluster linked to advanced mathematics skills, information processing, logic, analytical intelligence, concentration skills, obsession–compulsion and Asperger's syndrome. That cluster correlates very strongly.
and the bad news:
The hybridization was successful in the Stone Age, but the environment has changed. I found that modern culture selects for socialization but against the Neanderthal traits for mathematics and intelligence, ... I don't know how you'll survive when our genes are gone."
Feb'15 Apparently Asians got two helpings of Neanderthal genes.

Visiting Ceres in March

Not as dramatic as landing on a comet, but a first, just the same. In two months, NASA will orbit Ceres, the largest dwarf planet in the asteroid belt. The same craft has already orbited Vesta, the second largest. That sill make it the first craft to orbit two celestial bodies. Plus, ion propulsion (Apr'15).
Doubleplus: 7 other space highlights expected this year

Survivor Bias

http://youarenotsosmart.com/the-book/
Survivorship bias in a nutshell: If you look at a profession and think: "Wow, that is full of the most skillful, smart, dynamic and interesting people I've ever seen!", should you join that profession or avoid it? David McRaney says, "not so fast." The same thinking applies to aspiring actresses, WWII bombers and businesses.

Before you emulate the history of a famous company, Kahneman says, you should imagine going back in time when that company was just getting by and ask yourself if the outcome of its decisions were in any way predictable. If not, you are probably seeing patterns in hindsight where there was only chaos in the moment.

BTW, this is just one post. McRaney's blog (You Are Not So Smart) is full of long, interesting, thoughtful posts on how people think. He loves the counter-intuitive.

Don't Let the Bedbugs Bite

http://www.wired.com/2014/12/building-a-better-bed-bug-trap/
Our little corner of BC has been okay. But I am told North America is again plagued with bedbugs. Ironically, the worst places are often the most expensive addresses: New York, San Francisco and even Toronto are large cosmopolitan cities with strong environmental sensibilities. They attract people from all over the world, some of whom carry bedbugs in their luggage and they abhor the idea of effective pesticides (like DDT).
Those times may be over. Researchers at SFU may have found the magic formula that will attract bedbugs and thus allow them to be trapped. Their weakness is that they like to cluster together.

Mankind Leaps Again

https://twitter.com/ESA_Rosetta/status/532565327721545728/photo/1In mankind's journey into the universe beyond the planet, the greatest leap was the moon walk. Not only has there been no progress that size since, there have been few feats that were equal, or even comparable. (OK, driving a car on the moon wins). Huge events, nonetheless, include Sputnik, the re-usable space vehicle, private satellite launch and robots on Mars. This week has seen another milestone for the history book: landing a robot on a comet.
It had some problems, but what's cutting edge if it doesn't occasionally bleed? Maybe for the next mission, they'll reconsider the wisdom of solar power in the far solar system.
(Update Nov18/14) They were looking for organic molecules on the surface and they found them. We'll have to wait until the sunlight gets better before we get any more detailed analysis.

Fusion Heats Up

http://chemwiki.ucdavis.edu/Physical_Chemistry/Nuclear_Chemistry/Fission_and_Fusion
Lockheed Martin has caused a buzz this week by announcing* a nuclear fusion project.

Nuclear fusion is, of course the ultimate energy source: clean, safe and inexhaustible. It produces no carbon dioxide or pollution. It can't explode and produces no nuclear bomb making materials. There are about a thousand trillion tons of fuel, deuterium aka heavy hydrogen, available in the ocean.

Nuclear fusion looks like a sure thing at the multi-billion dollar ITER project. Unfortunately it won't happen until 2030+ and will cost $15+ billion. The LM project promises to be smaller, cheaper and sooner. The thing is: LM's project looks less feasible than General Fusion's. Their big advantage, as far as I see it is that Lockheed Martin can guarantee the funds to make the project happen while General Fusion has to beg for venture capital money. Making big announcements can be a strategy to dry up the other guy's funding.
