What's some of the coolest technology you've used?

  1. Jan 23, 2017 #1
    I'm not a physicist, so my answer is not glamorous, but I'm wondering what's some of the coolest technology you have used at work or in research?

    I am doing a temporary job where I am testing point of sale systems and their ability to handle various types of currency. I have some physical cards made with a card encoder, but I don't get to play with the encoder itself. Years ago I did get to play with a card encoder at a different job.

    Here I have a machine hooked up to a computer that can simulate any type of credit card (test cards of course, no real money involved). It may not sound exciting, but it's a really cool job, as we document issues with the system and are really a part of the process. My strong point is my ability to come up with new ways of breaking the system! (Before the customer does, one hopes).

    Of course, your answer may be "particle accelerator," but as you can see, I am curious about any neat gizmo that you have used that you thought was cool, even if you were the only one that thought so.

    in Biology:
    electron microscopes
    scanning electron microscopes
    confocal microscopes
    differential interference/fluorescence microscopes (I like small stuff)

    also pipetmen (and associated technologies): measures small volumes fast and accurately, with a new plastic tip for each measurement (avoids contamination)

    IR thermometer: useful and fun

    Fabrication:
    3D printer
    Milling machine

    Probably supercomputers, I used them for a massive simulation in college that required more power than the computer labs at the school could provide. I was also allowed to upload test programs to IBM's quantum computer.

    Neural networks I've recently discovered to be a really cool technology. I'm currently rebuilding several of my AI routines to use them. I've also become obsessed with genetic algorithms. They often come up with really unique solutions to problems that I never would have thought of, and outperform my carefully calculated solutions.

    Yes, I'm fascinating with GA's (and all the possible variants) also. (Ant colony optimization is neat. I haven't gotten really into it yet though).

    Stupid question - but I know what a neural network is in theory, but I don't know how it exists as a physical thing. Is it software that's running on a computer or supercomputer, or is there a physical "network" of something that you are using.

    It's software, I've never heard of any hardware accelerated NN, though it may happen in the future as they may start taking AI and simulation jobs in games.

    One of the coolest things I've used recently are these little deformable mirrors that have actuators at the back so you can make them different shapes to simulate astigmatism and other sorts of distortion.

    Do they have a name?

    Electric coffee percolator.

    Don't get me started on coffee devices. (oh, too late).

    I have an espresso machine, a stovetop espresso maker (sometimes called a moka pot), and a portable french press I use to avoid the terrible coffee that is served at most offices and workplaces.

    I get to play with dilution refrigerators with a base temperatures of 8mK...ls that cool enough:cool:

    Looks like you won this round.

    Can never have too many options for coffee.

    I read your response first thing in the morning, and promptly discovered that I've run completely out of coffee :frown: not an ideal start to the day!

    I am so sorry this happened to you. I hope by now this injustice has been resolved and never happens again.

    I recall estimating amounts of cut and fill using a topo map and planimeter.
