SCIENCE TUMBLR, EXPLAIN!

Hello that is a touch lamp and basically it uses something called capacitors to turn off and on. Capacitors in touch lamps store charges and when those charges are altered, they activate an oscillator responsible for turning the lamp off and on.

Humans have what is called body capacitance; we can store tiny electrical charges in our bodies and use them to activate touch sensors (which is why your phone’s touch screen works, too, and why it won’t work if you’re wearing cloth gloves that aren’t conductive), for example, altering the charge in a capacitor like the one in this lamp.

The cat doesn’t have enough body capacitance to set this lamp off, but it IS conductive enough to relay a human’s charge. So when the human makes contact with the conductive bare skin of the cat’s nose, their charge travels through the cat to the lamp through their toe bean, activating the lamp. Fur is not conductive, so it won’t do it when the human just pets the cat.

This explanation was all very sensible until “toe bean” and I am giggling with pure delight XD

From Racing Suits to Robotic Gloves: How to Gear Up with NASA Technology

Did you know you are surrounded by NASA technology? From your apartment building to the doctor’s office, and even in your cellphone camera, there is more space in your life than you think!

In the latest edition of Spinoff, we are introducing dozens of new ways NASA technology could cross your path. Whether you need an extra “hand” on the production line or a weatherproof jacket, check out how to gear up with technology made for space.

Grip-Strengthening Glove

Robots are crucial to exploring space and other planets – they could even support astronauts and form the advance party for places humans have yet to reach. But the human machine is hard to replicate.

A collaboration with General Motors helped us build Robonaut 2 – and the design for this robot’s hands has been adapted into a robotic glove that helps manufacturing employees, such as automobile workers, reduce injuries and improve quality control.

The Swedish company Bioservo used the Robo-Glove technology to create the world’s first industrial-strength robotic glove for factory workers who perform repetitive manual tasks.

The Ironhand glove adds force to the user’s grip with artificial tendons and pressure sensors on the palm and the fingers.

The result? Reduced strain on the user’s own tendons and muscles, meaning fewer workplace stress injuries and better comfort for workers.

Temperature-Control Fabrics

NASA astronaut Anne McClain displays a U.S. spacesuit glove that consists of several layers for extra thermal protection and comfort. Thermofoil heaters are also attached inside each of the fingertips in one of the layers of the glove.ALT

Spacesuits need major insulation and temperature control to protect astronauts on extravehicular activities, aka spacewalks. To help solve this, we created a phase-change material with help from the Triangle Research and Development Corporation.

With funding from a NASA Small Business Innovation Research contract, Triangle incorporated the material into a fabric glove insert that could maintain a steady temperature by absorbing and releasing heat, ensuring it feels just right.

While the invention never made it to orbit, it did make it into the driver’s seat.

Outlast Technologies exclusively licensed the material from Triangle and has incorporated it into outdoor gear, bedding, and now – auto racing suits with help from Cambridge, England-based Walero.

The race undergarments, bonded with fire-retardant material for added protection, help drivers maintain a lower core temperature and heart rate, which means fewer mistakes and better lap times.

The suits have been sold to both amateur racers and professional NASCAR drivers.

Lightweight Rain Jackets

Astronaut John Grunsfeld works on repairs to the Hubble Space Telescope.ALT

The superinsulating material that makes up space blankets is one of our most ubiquitous spinoffs. Found everywhere from inside the walls and roofs of buildings to cryogenic tanks and MRI machines, radiant barrier technology was first created to insulate spacesuits and spacecraft. And now this NASA spinoff can be found in weatherproof jackets as well.

Inspired by her passion to run following a series of surgeries to help correct a life-threatening injury, Hema Nambiar launched her Larchmont, New York, start-up company 13-One. To create her jacket, she worked with Advanced Flexible Materials Inc.’s brand Heatsheets. The brand was already marketing products like the space blankets traditionally distributed after races to prevent dangerous drops in temperature.

The resulting line of jackets has a black exterior and a lining to reflect body heat. They weigh less than a pound, are wind- and water-resistant, and easily pack into a small, built-in pouch.

Please, never let this meme die.

This is the best one I’ve seen so far

What kind of quantum fucking memeing from 2056 are you people beaming to us

It’s fucking back

shooting star. i can’t believe i’m hearing shooting star again in the year 2020

The fates have ordained that this cross my timeline again and you better fucking believe i’m reblogging it.

This is the only good meme, don’t @ me
