3D Africa Helps to Diversify STEM

Right now, you can drop a few thousand dollars on a 3D printer and start making your own plastic trinkets. We've covered these awesome machines at various places such as the Consumer Electronics Show, your favorite library, and the homes of charitable folk. Wouldn't it be awesome if 3D printers were available to a wider audience?

3D Africa is a project of Nigeria's Youth for Technology Foundation (YTF). The aim of the project is to help give young girls the skills and confidence to succeed in STEM, as well as encourage their entrepreneurial spirit. CEO Njideka Harry told Techcrunch that "There are cultural biases that hold that science is the domain of males and that it is not important for girls’ future lives and that girls are not as capable as boys when it comes to science learning.”

Africa has been exploited throughout its history, and the current generation still bears the brunt of history.  There are children, especially young girls, who are not properly prepared for careers to take them to the next level. According to Ideas Lab:

"Just as personal computers and the Internet empowered individuals and organizations to create new types of information technology-driven jobs, so will 3D fabrication technologies change the way African entrepreneurs do business by allowing anyone to make (almost) anything. Africa’s economies are not industrial-based, but rely instead on the exploitation and export of the continent’s abundant natural resources. For example, the trade relationship between Africa and China, under which Africa exports raw minerals and imports manufactured goods, is estimated at about $166 billion. 3D printing technologies will help African citizens generate income independent of these kinds of relationships."

Wanderers - Check Out This Short Film!

 

Wanderers is a beautiful short film that explores would life may look like when we colonize other planets. I'll let the film's author, Erik Wernquist, speak for himself:

"In ancient greek, the planets visible in the sky were collectively called "aster planetes" which means "wandering star". It also refers to ourselves; for hundreds of thousands of years - the wanderers of the Earth. In time I hope we take that leap off the ground and permanently become wanderers of the sky. Wanderers among the wanderers."

A Deep Sense of Loss #Ferguson #BlackLivesMatter

I previously wrote about the excessive use of tear gas against protesters in Ferguson, MO, where Darren Wilson will not face charges for killing unarmed citizen Michael Brown.  Unfortunately, tear gas was used recklessly again tonight, hitting peaceful protesters as well as journalists.

Brown is another name to add to the increasingly long list of unarmed men and women killed by police. There is no justification for killing someone that does not present an armed and dangerous threat.

This affects science and tech in many ways. The tear gas article mentioned earlier speaks to the scientific justification for using tear gas in a civilian area. Online technology such as social media has been instrumental in keeping the details of this case in the forefront of people's minds. 

Sadly, this adds to the potential science and tech contributors lost to unnecessary violence. Maybe 28 year old Akai Gurley would have inspired someone in his neighborhood to pursue a scientific path.

Maybe 18 year old Michael Brown would have ended up majoring in a science related field in college.   

Maybe 17 year old Trayvon Martin would have attached himself to science during his late high school and college years.

Maybe 12 year old Tamir Rice would have had a chance to enjoy science in middle school.

Black lives matter.

Time Is Not the Same for Everyone #Interstellar (Spoiler Free)

The movie Interstellar involves many interesting scientific concepts, including the fluidity of time. On Earth, time moves at the same speed for all of us – otherwise our watches would constantly need to change how fast they move.  However, time can change in two specific scenarios.

If someone is moving significantly faster than us on Earth

If someone is under the effects of more gravity than us on Earth

Astronauts on the International Space Station (ISS) experience this.  As they orbit the Earth, the gravitational pull keeps them in orbit, and makes them move much faster than we are on Earth.  As a result, they age less than us.

If the same astronauts wanted to head away from Earth at an extremely fast speed – near the speed of light – they would age slower than us during the trip.  If the destination was an object with more significantly more gravity than the Earth – like a black hole – they would continue to age slower while under the effects of increased gravity.

That’s the genius of media – you can enjoy the adventure and emotion presented in the movie, and OPTIONALLY it can spark a light of curiosity that leads one to further research.

Shouldn't that be what science education is about?

R.I.P. Michael Alsbury #SpaceShipTwo

(Note: Please donate to the Mike Alsbury Memorial Fund, as he leaves behind a wife and two small children ages 10 and 17.)

It's been a rough week for space travel. First, an unmanned ISS resupply rocket launched erratically and had to be destroyed by NASA safety operators. Next, the Virgin Galactic spacecraft SpaceShipTwo suffered a mishap that resulted in the loss of life. Pilot Michael Alsbury was killed when SpaceShipTwo crashed in the Mojave Desert while attempting to land.

Heroes like Alsbury put their lives on the line to push forward space research. It's critical that we not take this loss for granted, and they we can continue to push forward to support what Alsbury lived for - taking space exploration to the next level.

The Guardian has a nice writeup of Alsbury's accomplishments. From that article:

Alsbury earned a degree in aeronautical engineering from California Polytechnic State University, San Luis Obispo. He was the recipient of Northrop Grumman’s President’s Award for Innovation-for-Affordability Excellence this year.

Alsbury was a “home-schooled, home-brewed” pilot who earned his way up through the ranks at the company, starting as an engineer. Alsbury had also put himself through commercial pilot school and was certified as a flight instructor.

Scaled Composite, Alsbury's company of 15 years, released a short statement in his honor
