Why So Few? Women in Science, Technology, Engineering, and Mathematics. By Catherine Hill, Ph.D. Christianne Corbett Andresse St. Rose, Ed.D. “Just not interested”. Many girls and women report that they are not interested in science and engineering. In a 2009 poll of young people ages 8–17 by the American Society for Quality, 24 percent of boys but only 5 percent of girls said they were interested in an engineering career. Another recent poll found that 74 percent of college-bound boys ages 13–17 said that computer science or computing would be a good college major for them compared with 32 percent of their female peers (WGBH Education Foundation & Association for Computing Machinery, 2009). From early adolescence, girls express less interest in math or science careers than boys do (Lapan et al., 2000; Turner et al., 2008). Even girls and women who excel in mathematics often do not pursue STEM fields. In studies of high mathematics achievers, for example, women are more likely to secure degrees in the humanities, life sciences, and social sciences than in math, computer science, engineering, or the physical sciences; the reverse is true for men (Lubinski & Benbow, 2006)… Among first-year college students, women are much less likely than men to say that they intend to major in science, technology, engineering, or math (STEM). By graduation, men outnumber women in nearly every science and engineering field, and in some, such as physics, engineering, and computer science, the difference is dramatic, with women earning only 20 percent of bachelor’s degrees. Women’s representation in science and engineering declines further.

What is the Basic Difference Between Facebook, Linkedin and Twitter?

12 Saturday Jul 2014

Posted by bunchofopinions in Social, Tech

  • Typical social networks have been built around ideas like who you already know (Facebook) and where you’ve worked (LinkedIn).

  • We’ve made Twitter into a tool that allows us to connect with and interact with people based on the kinds of stuff we share.

    ~A new kind of network, by David Aron Levine

David Aron Levine further wrote: “However, it wasn’t built around this concept exactly. It was really built around the idea of making it easy to share quick updates with people we know. (Remember: the concept of a “re-tweet”, an @ reply, and “hashtags” came from the community). The fact that we’ve collectively hacked it for the purpose of sharing and connecting with a new group of people might say more about our demands than it does about the service itself.”

Yes, there was a demand, but the main question still exists: how did it happen? The answer is … characters’ limitation.

We can’t express ourselves by more than 140 per twit. As Charles IX wrote in this context about half thousand years ago, “horses and poets should be fed not fattened“.

In other words, the Twitter’s basic feature – that David Aron Levine is discussing – appeared as one of the side effects of the above meant technical limitation.

Two key factors that makes Silicon Valley such fertile ground for startups.

The most important legal factor is the California State ban on Non Compete Law:

    … a very special law was enacted in California in 1872. The law in question declared null and void any contract between a business owner and employee if said contract in any way restricted the employee’s freedom to change employers, even if that meant joining the former employer’s competition.

    In other words, any previously signed agreements—for example, an employee contract signed upon hiring—that could in any way limit the employee’s right to freely choose his or her place of work were deemed unenforceable in this 1872 law. More specifically, those clauses that were in conflict with this law were deemed unenforceable.

    This law was initially ratified in 1872 as part of California’s Civil Code. It is now listed under California Code – Section 16600, also known as CAL. BPC. CODE § 16600, and reads:

      Except as provided in this chapter, every contract by which anyone is restrained from engaging in a lawful profession, trade, or business of any kind is to that extent void.

    As a result of this cascade of direct and indirect consequences from the application of this law in Silicon Valley, today a number of generally operating U.S. legal standards, including some of the most important, are practically blocked (“de facto” canceled). Read more: From the Gold Mines of El Dorado to the “Golden” Startups of Silicon Valley

    The above California law was recently tested during the Hewlett-Packard special experimental research: NDA Experiment Set up by Mark Hurd.

The most important among Silicon Valley startups motivation factors is the “not afraid to fail” attitude:

    Perhaps one of the first practical application of this attitude was formulated about 22 centuries ago.

      “A mistake in choosing the right way of actions should be punished less than omission”
      ~ Roman army, 200 BC

     

    Two thousands years later people still continue to look for some of the alternative approaches that can bring the positive results as well:

      “When teachers tried to motivate students with scare tactics that reminded them of the negative consequences of failing, this backfired and resulted in poorer performance in high-stakes exams”.
      ~ School Psychology Quarterly. American Psychological Association Press Release.

    See also, a bit more detailed description of the same phenomenon:

      “Our results indicated that the frequency of omission increases when punishment is possible. We conclude that people choose omissions to avoid condemnation and that the omission effect is best understood not as a bias, but as a strategy”.
      ~ The Omission Strategy. Peter DeScioli, Brandeis University, Departments of Psychology and Economics

What are these two images clarify? Any Bill Gates – as well as Eric Schmidt – will finally win a competition with any Jim Clark or even Tim Cook. This is a matter of time only. As people sometimes say in UK, association “football is a simple game; 22 men chase a ball for 90 minutes and at the end, the Germans win”.

For these reason Steve Jobs had to – and would be able – create a new niche every 3-5 years, and this is a main challenge for Tim Cook now…

To Those Who are Concerned About the “Global Warming”

10 Tuesday Jun 2014

Posted by bunchofopinions in Politics, Science, Tech

≈ Leave a comment

    According to astrophysicist Joseph Shklovski (lectures, 1981) the total level of energy produced by human civilization during the last 300 years of industrial revolutions, is still about one hundredth of a percent of the total energy flow that reaches the surface of the earth from the sun. Meanwhile in recent decades of info-tech revolution, the total level of energy that earth irradiates to space comes to a million times more than it would have done naturally as the planet heated to 300 K. From this point, for the last couple of decades, Earth outran planet-giants Jupiter and Saturn and became comparable to Sun. So, for a radio-telescope’s observer from outer space, the earth’s info-tech revolution looks like the birth of a new bright star on the cold Earth-planet. Source: ‘National Information Resources‘, by Gregory Gromov,  Nauka, 1984, p.15

On top of radio transmissions discussed in 1981, there are now 6 billion active cellphones worldwide…

In spite of all of the above, there are still so many people who generously and selflessly donate their time, energy and money to so-called “Global Warming” initiatives and … nobody cares about the real issues like “self-destruction as a result of a thermonuclear catastrophe or some other discovery which may have unpredictable and uncontrollable consequences“.

Sniper Attack [in California] Knocked Out Substation, Raises Concern for Country’s Power Grid. The incident happened one day after the Boston bombings which is why there’s been little reporting on the incident. Now authorities say the damage is the work of a sniper and they are treating the shootings an act of terror. “It appears to be very well organized and very well planned,” said Steve Harrison of the Arizona Department of Public Safety. In just two hours in the middle of an April night last year, a militarystyle sniper attack took out 17 transformers powering the Silicon Valley… Security expert Norman Beasley says power stations can easy pickings for bad guys because they are out in the open… The FBI continues to investigate the attack, but no arrests have been made.

Blackout a reminder of power grid vulnerabilities. Associated Press. SAN DIEGO — A blackout that swept across parts of the Southwest and Mexico apparently began with a single utility worker and a minor repair job. How it then rippled from that worker in the Arizona desert, to southern California and across the border, plunging millions of people into darkness, has authorities and experts puzzled, especially since the power grid is built to withstand such mishaps. However it … was a reminder that the nation’s transmission lines remain all too vulnerable to cascading power failures. “There are a lot of critical pieces of equipment on the system and we have less defense than we think,” said Rich Sedano at the Regulatory Assistance Project, a utility industry think tank based in Montpelier, Vt. … There have been several similar failures in recent years.

U.S. Risks National Blackout From Small-Scale Attack. Federal Analysis Says Sabotage of Nine Key Substations Is Sufficient for Broad Outage. The U.S. could suffer a coast-to-coast blackout if saboteurs knocked out just nine of the country’s 55,000 electric-transmission substations on a scorching summer day, according to a previously unreported federal analysis… “This would be an event of unprecedented proportions,” said Ross Baldick, a professor of electrical engineering at the University of Texas at Austin… Sabotage could wreak worse havoc, experts said. “The power grid, built over many decades in a benign environment, now faces a range of threats it was never designed to survive,” said Paul Stockton, a former assistant secretary of defense and president of risk-assessment firm Cloud Peak Analytics.

National Research Council worried that a well-coordinated attack on the grid “could deny large regions of the country access to bulk system power for weeks or even months.

The elevators were a tragic exception to an otherwise successful evacuation that resulted in the survival of 99% of the people who worked below the floors where the jets crashed… Newly installed safety devices condemned many people to death. To comply with building codes, the World Trade Center since 1996 had been adding locks that made it impossible for passengers to force open the doors of stalled elevators. These locks, called “door restrictors,” had been added to about half of the 198 elevators in the twin towers. Nobody is known to have escaped from an elevator locked by a door restrictor.

3D Printer For Makeup

≈ Leave a comment

3D printing is all the rage these days, but for now, it’s mostly centered around little plastic doo-dads. The Mink ,,, is a bit different. The little printer lets users choose any color on the web, or in the real world, and using simple already-existing software, print that color into a blush, eye shadow, lip gloss or any other type of makeup… Moreover, drug stores offer an incredibly limited selection of colors and options. Because makeup isn’t the main driver of sales in a Walgreens, they get more universally loved colors like pinks and reds, and exclude consumers who want to be bold. More niche retailers like Sephora have a wide selection of colors, but at a much higher price. With Mink, users can satisfy the desire for instant gratification while still having access to any color in the world at an affordable price… The Mink costs less than $200, with plans to launch later in the year… Read more: http://techcrunch.com/2014/05/05/mink-is-a-3d-printer-for-makeup/

The organizations, including The Associated Press, filed a brief with the National Transportation Safety Board in support of aerial photographer Raphael Pirker. Pirker was fined $10,000 by the FAA for flying a small drone near the University of Virginia to make a commercial video in October 2011… Media organizations are intensely interested in using drones for photography and videos because they are far less expensive to buy and operate than a manned airplane or helicopter, and because their size and versatility provide visual perspectives often not possible with manned aircraft.

What ‘4-D Printing’ Is

09 Friday May 2014

Posted by bunchofopinions in Tech

≈ Leave a comment

4-D printing takes “smart” materials from a 3-D printer that can assemble themselves. So instead of just printing out a chunk of shaped plastic, you can actually create shapes that a fixed 3-D printing nozzle couldn’t accomplish. The potential uses for this range from extreme condition architecture to adaptive infrastructure, like pipes that expand and contract depending on water volume. There’s also potential in medicine: various implants could be inserted in a packed form, then take their true shape once they reach their destination.

That’s the provocative question being debated in antitrust circles in the wake of revelations that Mr. Jobs, the co-founder of Apple, who is deeply revered in Silicon Valley, was the driving force in a conspiracy to prevent competitors from poaching employees. Mr. Jobs seems never to have read, or may have chosen to ignore, the first paragraph of the Sherman Antitrust Act: Every “conspiracy, in restraint of trade or commerce” is illegal, the act says. “Every person who shall make any contract or engage in any combination or conspiracy hereby declared to be illegal shall be deemed guilty of a felony, and, on conviction thereof, shall be punished by fine” or “by imprisonment not exceeding three years, or by both said punishments.”

… Cyber Command, currently staffed by 1,100 people … The main concerns are cyber attacks from nation states such as China or Russia that could create massive power outages in the United States, or an attack on U.S. financial networks, such as stock exchanges and financial institutions, that could cripple the economy… U.S. military personnel also lack training and readiness needed to confront advanced cyber threats, Alexander added, and military commanders lack confidence about what levels of risk are acceptable in the cyber domain. They also lack a “reliable situational awareness”—military jargon for knowing what is in the battle space, globally or in U.S. military systems, he said… Adm. Cecil D. Haney, commander of the U.S. Strategic Command, which is in charge of Cyber Command, also testified at the hearing that cyber threats are increasing… Haney said plans call for creating 133 “cyber mission teams” staffed by over 6,000 people by the end of 2016. So far 17 teams are deployed in a variety of missions within combatant commands and at Cyber Command headquarters at Fort Meade, Md.

Under normal operation (not the end of the world), I collect used engine oil and fuel from changed filters off Peterbilt trucks I service (roughly 120 trucks). I filter and blend this used oil with a setup at my house that I will detail later. However, in a SHTF scenario, the theory would be collecting the engine oil and automatic transmission fluid or even power steering fluid from abandoned vehicles, which will have run out of fuel on the road, to make a custom blend of usable emergency fuel for your diesel… The proper vehicle to run this fuel would be one with a mechanically-injected older diesel engine, pre-1997 would be safest. All older IDI Fords, 6.9 l and pre-powerstroke 7.3 l engines do well on it.

Lessons From Negotiating With Steve Jobs

… I had pitched 15%, our standard. Steve pointed at it and said, “15%? That is ridiculous. I want 50%.” I was stunned. There was no way I could run my business giving him 50% of my product revenues… I had to make the business make sense financially. I just needed to make my 15% look like his 50%. To do so, I reduced the nut to split by first deducting the cost of packaging, of technical support, the salaries for some developers on my side of the business to implement fixes, and when I still couldn’t get the math to pencil out, I added a $6 per unit ‘handling fee’ thanks to some inspiration from an infomercial on the Home Shopping Network. My new “Hollywood net” number read 50%, but fully-loaded it was pretty close to the 15% of gross I needed to make the deal work. Magic! Steve was happy with his 50% contract and the deal got inked…

… when asked why Robert Cailliau wasn’t credited with co-creating the Web, Berners-Lee said this was because he hadn’t.
“Robert didn’t invent it. I invented it by myself, and coded it up on a NeXT, but Robert was the first convert to it, and a massive supporter,” he explained.  “He got resources together at CERN, helped find students, gave talks. He also later wrote some code for a Mac browser called Samba. He also put a lot of energy into persuading the CERN directorate that CERN should declare that it would not charge royalties for the WWW, which it did in April 1993.”
