Japanese people take their calculators very seriously.
What they need to do is figure out how to put their facts and figures in electronic form. Maybe using a "computer" running a "program" that adds figures up in columns and rows like a "spreadsheet".
Neuroscientist Explains 1 Concept in 5 Levels of Difficulty
I'm a bit surprised the grad student or expert didn't discuss neuromodulators more. The fact is we already have the full connectome of a much simpler system, a worm (C Elegans). And this full mapping is considered insufficient to fully understand the simplified worm behavior because it doesn't fully capture the diversity of different neuromodulators and how they effect processing in neurons. It matters if the neuron is releasing dopamine, serotonin, glutamate, etc. There are ways to approximate these from EM images by analyzing the synapse properties, but ultimately it leads to a much larger problem in understanding neural processing.
In a similar light, the connectome project does not do a good job capturing synaptic strength. We don't really know just from the electron microscopy how strong the connections are. We can try and approximate it by looking at the size/formation of the synapse but ultimately this falls short.
For instance, my memory is that thalamocortical projections (thalamic nuclei to L4 of the cortex) do not make up the primary inputs to L4 on a structural connectivity level, but the strength of those connections are much stronger then the more numerous cortico cortical connections. I don't think the connectome from EM images will be able to pull that out.
The connectome is important, the same way knowing the human genome is important. However, it's really not going to tell us how to simulate a person. It's an important step to be sure, one we are still a good ways away from finishing last I checked (which was three years ago ...)
Why these LEDs glow at all?
Chemical reaction, turns the orange into a battery. LEDs only need 1-3V to turn on so you don't need a very strong reaction. I noticed some of the pins are darker colors, Mr Glove probably dipped one leg in a dissimilar metal or another chemical so the electrons want to move from one pin to the other with the acidic juice as the electrolyte. Look up potato battery for similar experiments.
Tiny Fennec Fox Kit Born at Sydney's Taronga Zoo
I think it's afraid of the camera because it can hear the electrons moving in the CCD.
Adam FAILED to Ruin Tesla
These guys make a start at assessing the energy/carbon cost, but stop well short of completing the job. What is the life-cycle carbon cost of PV cells used to produce the electrons; what is the life-cycle cost of the storage of electrons prior to going into the EV, etc. Only then can you make an honest carbon balance sheet.
Label rewinder (Comedy Talk Post)
*ban
Visit this site https://www.adazonusa.com/other-products/label-rewinders.html for more information on Label rewinder. Barcodes are becoming exceedingly popular as an electronic system of identification. They need to be generated using special software and then printed with the aid of a barcode printer. It can be easily categorized into two types based on the printing methods that are thermal transfer based printers and direct thermal based printers.

Eroding Electoral Confidence | Full Frontal with Samantha Be
I have to strongly disagree with her last points on the recounts in Wisconsin etc - if there's an appearance that the results are in any way suspect, a recount is entirely reasonable. It's quite well established that many of the electronic voting machines in use throughout the country are in fact vulnerable to tampering, and if we can document any instances of that actually occurring that's only for the good. We *shouldn't* have full faith in election results when they're susceptible to manipulation, and should audit them regularly (either when things smell funny or just randomly).
Grappler Police Bumper - No more PIT maneuver
All this James Bond gadgetry works perfectly in controlled test environments. Just like that mobile device that the chase vehicle dispatches to drive under the suspect's car with an antenna to short out the car's electronics and bring it to a stop. I'll believe it when I see any of this used effectively in the chaos of a real world pursuit.
Is This What Quantum Mechanics Looks Like? - Veritasium
To be fair, you were taught this in school if you were taught wave particle duality and the double slit experiment. Look at this. Now imagine a particle bouncing along in very small steps (quantum leaps if you will), and the direction it goes depends on the strength and orientation of the wave where it lands. You may never have been told to think about it like that, but that's what makes physics so amazing that sometimes all it takes is for someone to think about it slightly differently. The information was there all along, but who would imagine the 'particle' bit of an electron interacting with the 'wave' bit - the electron interacts with itself?
I absolutely love it, it's amazing, and simple and beautiful. It may provide insights into new ways we can model quantum behaviour, it might open up new questions to ask.
There's things I'd like to know. First, if the standing waves generated at each step in the droplet's progression interact with each other, the droplet is reacting according to waves it made in the past - what implications does that have for the notion of real particles in a spacetime continuum? For the double slits experiment to work in that model - in the ball on a rubber sheet sense - the sheet would have to stay warped to some extent after the ball had passed. In the quantum sense of the real double slits experiment, we would say it IS a wave, passes through both slits and appears according to statistical probability (the diffraction pattern).
Presumably several droplets released along the same path would go on to take a different route through the slits, to create a diffraction pattern as it must. Perhaps because of fluctuations in the temperature or density of the water at different locations? Is that a limitation of the model or an indicator about the nature of the fabric of spacetime? Perhaps even due to quantum fluctuations in the water particles - the water is never the same twice even if its perfectly still each time - which would potentially mean we're cyclically using quantum mechanics to explain quantum mechanics and we actually haven't explained very much.
The philosophy bit: But this reaches to the heart of the issue with quantum mechanics and perhaps science in general. How accurately can we model reality? The reality is beyond our ability to see, so we can only recreate simpler versions that are always wrong in some way... our idea of what happens - our models - can never be 100% because only a particle in spacetime can perfectly represent a particle in spacetime.
Scientific results and definitions are always defined with limits - "it works like this, within these confines, under these conditions, with these assumptions." There are always error margins. We are always only ever communicating an idea between different consciousnesses, and that idea will never be as true to life as life itself.
Sorry for the wall of text, it's a great and provocative experiment.
I hate quantum mechanics and the absurd implications that extrapolate from it. I always believed that one day we would look back and laugh at how wrong it was. Turns out a more reasonable competing theory has been there all along. Why was I not taught this in school.
I get that it's just another theory and that quantum mechanics can't be judged based on intuition that comes from our interaction with the macro world. Still...fuck quantum mechanics.
Bill Maher - New Rule - The Danger of False Equivalency
False equivalency that all electronic music sounds the same.
Working Miniature V8 Paper Engine
I think my point was missed here.
It is impressive - no argument there.
But it's not an engine, and couldn't run anything. It's powered by an outside source. It doesn't create energy, it's the recipient of energy. I suppose if you want to credit it as a motor, you could credit it the same as an electronic motor, which uses outside energy, but not as a V8 engine which generates it's own energy.
BMW Concept Bike
So i'm obsessing on the piece of electronics @1:18. Id like to figure out exactly what it is model wise. It has Akai VW meters and directional play arrows. I have to assume that it's an Akai cassette deck with auto reverse. Anyone have a clue what model it might be.
I find it odd that in the future they will be using cassette decks
Senator Warren Destroys Wells Fargo CEO Over Cross Selling
Awesome comment. I wish I could upvote it twice. I threw up a little in my mouth watching the grandstanding going on here and how apparently most Sifters are eating it up.
Fraud? Cross-selling is perfectly legal and in fact practiced regularly in many industries besides banking (like when Best Buy tries to get you to purchase a protection plan for any electronics you buy at their store). If she has an issue with it, as a legislator she is free to bring a bill to the floor to do something about it. The problem is, she didn't give a shit about cross-selling until she realized she was going to have an opportunity to stump for future votes in these hearings and she apparently doesn't give a shit about it now because despite those strong-worded pleas for action she's done nothing personally to make anything she said happen.
Stumpf should give up his money? He isn't the one who opened fake Wells Fargo accounts nor is there any evidence he directed his employees to do so. And as he tried to explain before she cut him off to grandstand some more, those fake accounts only represent 1% of the total cross-selling that happened, which means the stock price was not unduly inflated--people were in fact opening of their own volition more accounts with Wells Fargo than any other bank and Wall Street loved them for it.
The real issue here is that there were not adequate controls in place to prevent the fake accounts from being created in the first place (or detected quickly after being created). And for that Stumpf probably does have some small amount of responsibility, although it sounds to me more like whoever was in charge of compliance is the person who likely should be the one left holding the bag.
But let's not let reality get in the way of a politician's dreams of future offices.
She is: This entire thing, and all of the clips like it, and all the media coverage she's received for the past year are a political-strip-tease. She's only doing this to set up the strongest possible position in 2020/24. These are planned dog-and-pony shows.
It should matter more that she's not actually doing anything here, but judging by the comments she doesn't have to bother.
Are You Ready To Be Outpaced By Machines? Quantum Computing
One of those "problems conventional computers can't solve" is factoring primes (OK, they can, but it's very slow).
Quantum computers could make this very quick.... Which actually kinda sucks. Because, in a very simplistic sense, all encryption and by extension all electronic transactions depend on factoring primes being hard to do.
Basically quantum computers are going to break the Internet the second they become widely available.
