Giving a Kid a Hand – Literally

Non-profit Limbitless Solutions, founded by student Albert Manero, has started a project #3DHope: changing lives through the design and distribution of 3D printed limbs.

Below is a lovely video of Iron Man Robert Downey Jr giving an arm to a young boy. An awesome example of what the “opening up” of 3D printing technology (initiated by the Adrian Bowyer, Vik Olliver and the others in the original RepRap project) can accomplish for people’s quality of life.

Dawn Spacecraft Becomes First to Orbit a Dwarf Planet | NASA

NASA’s Dawn spacecraft has become the first mission to achieve orbit around a dwarf planet. The spacecraft was approximately 61,000 kilometres from Ceres when it was captured by the dwarf planet’s gravity at about 4:39 a.m. PST (7:39 a.m. EST) Friday.

“Since its discovery in 1801, Ceres was known as a planet, then an asteroid and later a dwarf planet,” said Marc Rayman, Dawn chief engineer and mission director at JPL. “Now, after a journey of 4.9 billion kilometers and 7.5 years, Dawn calls Ceres home.”

In addition to being the first spacecraft to visit a dwarf planet, Dawn also has the distinction of being the first mission to orbit two extraterrestrial targets. From 2011 to 2012, the spacecraft explored the giant asteroid Vesta, delivering new insights and thousands of images from that distant world. Ceres and Vesta are the two most massive residents of our solar system’s main asteroid belt between Mars and Jupiter.

Girls in Maths and Science

In a piece on a new OECD study in The Guardian it is noted that

school performance could be boosted by parents encouraging girls to consider careers involving subjects such as engineering

and quoting the report directly:

“Gender disparities in performance do not stem from innate differences in aptitude, but rather from students’ attitudes towards learning and their behaviour in school, from how they choose to spend their leisure time, and from the confidence they have,” the report said.

That quote gets, I think, closer to what’s actually going on. It also identifies that girls actually score higher on maths and science, yet fewer continue with it in the senior high school years, and study a STEM subject in university.

Indeed, parents and schools have an important role to play. From my own observations, lots of kids have an interest and potential for STEM topics, and the key is to enable and feed that interest and not sabotage it with unfortunate stereotyped remarks and many other unhelpful little things (that affect confidence).

You get the odd argument that maths & science are not cool. Well, kids these days play with all the cool technology, right? There’s the Internet, online games, tablets, and so on – and 3D printing, robotics, and much more. It would be rather odd to say that those things are cool, but the people who research and develop these things are not…

I think the issue with that originates with an idea that exists in some schools that it’s (for instance) science vs sports, and that does help us in exploring as to what’s going on there. With sport, you can see very directly what benefit kids get out of it, what they learn is directly applied and visible.

Often, STEM subjects are taught in a dry fashion, and kids indeed wonder what use it is learning all that stuff. We do appreciate that it’s a challenge for teachers to deliver an interesting program (let alone hands-on) program if the resources aren’t there to support it. This is of course even more problematic for kinaesthetic learners.

This is why we develop materials and programs for STEM subjects. With the use intrinsic to the process, kids want to explore more! Girls as well as boys.

Awesome Chemistry: Volcano Squid

Burning NH4Cr2O7 with HgSCN. Nicknamed “lucifer’s squid” this experiment is actually two reactions taking place:

  1. the decomposition of ammonium dichromate which results in the jet black volcano.
  2. The second is the combustion of mercury (II) thiocyanate, which causes the enormous “tentacles” to appear from within the mound.

By the sound of the kids in the background, the video appears to have been made in Slavic language country. It’s funny to hear them exclaim the word “Kraken” when the tentacle-like structures erupt (Dr Seuss mentions a Kraken in “Oh the Places You’ll Go”).
