*in my most woo voice*
yeah, i study the harmonics of crystals' natural energy resonances. this one is titanium:sapphire
anyone build anything cool lately?
If you're a engineer looking for new challenge and to work with a great team, share your portfolio/projects/website/youtube with me or @cslorer
We work on nearly every type of problem from robots to chemistry.
Pics > words.
We hire hands-on, inventive, optimistic, fun engineers
I remember in the summer of 2007 when I was 14 or so, some of the kids in my class were watching a video of Saddam Hussein's execution. I turned away and left the room out of some similar instinct as expressed here by Damien. Don't do this to yourself
I’ve had a lot of people asking me about the botched execution of Christa Pike in Tennessee, as well as the upcoming execution by firing squad that’s supposed to be livestreamed. Having spent nearly 20 years on death row, my thoughts and feelings about these things are so vast that I sometimes struggle to find a place to begin. I became close friends with a man who had committed murder. He was like a brother to me. I once watched him break down crying, trembling as he told me he wished he was as evil as the world believed him to be, because then he wouldn’t have to care about what he’d done. Fifteen years later, he was still having nightmares about it. I know in my soul that he would never hurt another person again. But I’ve also watched a man being stabbed to death in prison. I cried for days afterward, and something inside me was changed forever. I learned that some people are capable of extraordinary transformation, while others remain capable of terrible violence even behind prison walls. There are no simple answers here. No slogans or political arguments that can adequately address the complexity of human beings, guilt, punishment, and suffering.
But there is one thing I want to say about the upcoming execution by firing squad. Don’t watch it. Whatever you believe about the death penalty, even if you think the person being executed deserves to die, don’t watch it. You cannot witness a human being being killed and simply walk away unchanged. What you see becomes part of you. It follows you into places you never expected it to reach. There are things I witnessed in prison that I would give anything to forget, things that still cast a shadow over my life decades later. There’s a difference between understanding that terrible things happen in the world and deliberately making yourself a spectator to them. I don’t have all the answers about justice, punishment, or forgiveness. But I do know that killing another human being should never become so ordinary that we turn it into something to watch from the comfort of our living rooms.
Any areas that are purely logic dependent (math + cs) are progressing quickly. Areas that need contact with reality (sciences, medicine, and engineering) will progress much more slowly. My guess is mathematical physics will show significant progress soon
Let the experiments begin
Replying to @Isaac__kim
We'll need a pipeline for new conjectures.
Or turn everyone into experimentalists.

There should be a frontier lab that takes Experimental Physics seriously
I did not know they were out here awarding Nobel prizes for nanocars. Forgive me chemistry, I was not familiar with your game
How does it work? Each "wheel" is a ratchet: excite it with a photon or electron into an unstable state, and the molecule's chirality forces it to relax by twisting in a particular direction. This causes the car to drive forward every time you hit it with an electron pulse
If you're curious, the 2016 chemistry Nobel was awarded to this paper's senior author, Ben Feringa, for molecular motors. Read about his self propelled nanocar here: doi.org/10.1038/nature10587
These images were taken with an atomic force microscope (AFM), which drags a cantilevered tip across the sample and uses a laser to read out small changes in the tip's position. This particular AFM tip was functionalized with a CO molecule, making it sensitive to individual atoms
It's kind of amazing that no one had seen an individual molecule until 2009. Check out the original measurements here: doi.org/10.1126/science.1176…
