"Z2" - Upgraded Homemade Silicon Chips

noims says...

That's fantastic. I got a reasonable understanding of semiconductor physics and chip layout in college, but seeing it actually physically happen just made a lot of it click together... 30 years later!

Maybe it's just me, but I think this deserves a *promote.

The Big Misconception About Electricity

spawnflagger says...

In general I love the Ve channel, but I think this video does more to confuse people than to enlighten them.
Also, no mention of "holes" (even though that's more part of semiconductors).
Also, of the multiple-choice answers, there wasn't one corresponding to 80% speed of light which is the measured speed of electrical signal in copper (depends on the cable itself, frequency, and other factors).
And if all of the power actually travels through the air, then why does the ampacity of a cable matter at all? Tesla could be quick-charging with flimsy cat5 cable!

A 100 Tesla non-destructive magnet has a major effect on a wide range of science. It's a one-of-a-kind tool for studying the fundamental properties of materials, from metals and superconductors, to semiconductors and insulators.


Icy achoo dither.

The American Sucker

NetRunner says...

How silly.

What economic issue is it that this video is claiming is the Fed's fault?

Income inequality? Good argument for a more progressive tax, and a larger system of social welfare.

Fraud? Good argument for a strong regulatory regime for banks, and a Fed chair who's got a basic mistrust of corporate greed.

Inflation? Maybe, but it seems like low, constant inflation is a good thing in everyone's theory of macroeconomics, and a central bank is a key tool for keeping your inflation where you want it.

Unemployment? Maybe, but again, fixing your money supply to some constant (e.g. pegged to the dollar, or the dollar pegged to gold) takes a big tool for managing unemployment out of your toolbox.

Mostly though, people need to remember that all money is ultimately fake.

Gold is just as worthless as paper money -- you can't eat it, you can't smoke it, you can't drink it, you can't even use it as a raw material for anything useful unless you're a jeweler, a dentist, or a semiconductor fabricator (and even then, you really should use something more common like copper or tin).

Money is a consensual hallucination meant to keep us all working. I'm really, really sorry if you reached adult age thinking that stuffing cash into your mattress was the route to riches.

Rich people understand that cash is intrinsically worthless. It's why they invest, rather than build giant Scrooge McDuck-style money bins full of coins.

All money is the same, whether it's in the form of stamped $20 gold coins, promissory notes (i.e. a green piece of paper that says "this $20 bill can be redeemed for an ounce of gold at the US treasury office"), or fiat currency, it's only worth whatever you can buy with $20.

Part of basic financial literacy is understanding that the overall trend is for prices to go up, and therefore that if you aren't getting a raise equal to or greater than the inflation rate every year, you're taking a pay cut.

Which is a good argument for unionizing, even if you're a salaried professional...

Neill Blomkamp of District 9 Talks about (real) aliens

spawnflagger says...

Yeah, Carl Sagan made the same exact point in the 70's, but only took about 3 sentences.

...and you cannot turn every single piece of matter into a computer or "thinking matter". He should look up the definition of a semiconductor. Even if AI becomes smarter than humans, they can't change the physics that govern the universe.

The Simpsons take on Ayn Rand & Right-Wingers

>> ^chilaxe: Statistically speaking
If you are going to speak statistically, show us the numbers. I would honestly like to see them, but I doubt they exist.

Yes, there probably aren't any statistics available, but media coverage generally regards Rand's followers as skewing toward self-reliant, libertarian types who emphasize performance.* It would be surprising if an ideology that glorifies self-reliance wasn't associated with increased self-reliant attitudes.

I think it's generally most rewarding for people to read everything, with the goal of being 'informationally a mile wide,' but those who are disinclined are free to reject the lessons in objectivist themes. IMHO, that just means more advantages available for those who draw from a broader sample of the marketplace of ideas, and that's really how the system is supposed to work. So rail against objectivism to your heart's content

Many business leaders say Atlas Shrugged influenced their lives more than anything else they have read. Joe Stafford, the 40-year-old CEO of supply chain management company IC Solutions, said he was a liberal before reading Rand at 23. Chip Joyce, the 31-year-old president of Ulla Bazant, a maker of high-end women's apparel, says the book has been his "frame of reference." http://www.usatoday.com/money/companies/management/2002-09-23-ayn-rand_x.htm

Hugh Hefner and Supreme Court Judge Clarence Thomas found Rand fascinating. Dallas Mavericks owner Mark Cuban and Whole Foods CEO John Mackey both cite Rand’s books as influential, though Mackey has said he doesn’t believe businesses exist solely to make a profit and selfishness is a virtue. In Silicon Valley, Rand’s ideas appeal to generations of entrepreneurs who built the computer industry and the Internet. T.J. Rodgers, CEO of Cypress Semiconductor, is a notorious Rand fan; Patrick W. Grady named his company Rearden Commerce after the steel magnate Hank Rearden from Atlas. http://www.bnet.com/2403-13056_23-272467.html

Super diamonds may replace silicon.

demon_ix says...

They have an inherently superior material that can take away the overheating problem engineers face today at every aspect of miniaturization and you're presenting a technical difficulty to the manufacturing process...

From wikipedia:
Natural blue diamonds containing boron and synthetic diamonds doped with boron are p-type semiconductors. N-type diamond films are reproducibly synthesized by phosphorus doping during chemical vapor deposition. Diode p-n junctions and UV light emitting diodes (LEDs, at 235 nm) has been produced by sequential deposition of p-type (boron-doped) and n-type (phosphorus-doped) layers.

What Are 13% of Americans Afraid of?

joedirt says...

Seriously guise.. Babbage and Turing? If only my computer was an electromechanical device the size of a house. Have you ever heard of a semiconductor? And the internet is clearly came out of mostly US military, US Universities and US silicon valley. Also, nothing Comedy Central does is funny, it's a joke and more like ironic humor that they are called Comedy Central (it's dark humour).

Also, how about sugar, tomatoes, potatoes, corn, cocoa, hot peppers, turkey, beans (except the blackeyed pea), pineapples

Enjoy your non-American cuisine jerkops.

Ball control on a touch screen (Microchip microcontroller)

Technically, a micro-controller execute opcodes. A microchip is a discrete packaged semiconductor. You could have an FPGA micro-controller, embedded microcontroller, etc.
In this case it was a FLeX embedded controller from Microchip Technologies Inc.

I added the line: "Controlled by a microchip micro controller" to goad him.

Clarkson Kills a Corvette... With a Helicopter

rychan says...

The Corvette is a colossal piece of crap and a near perfect example of why I wouldn't buy an American car. I'm an American and I know well how stupid most of us are.

Luckily engineering in America isn't done democratically, so I think your logic is faulty.

The US has the best higher education in the world, and the best engineers in the world. But frankly, the most talented mechanical and electrical engineers are probably more interested in building space equipment, nuclear submarines, fighter jets, supercomputers, or even helicopter gunships.

Compare this to 1980 Japan, where their brightest mechanical engineers would build either robots (smallish industry) or cars, because there wasn't much of an aerospace, defense, semiconductor, or space industry.

These days I think Europeans (EADS) and Japanese have more space, semiconductor, and defense industries attracting talent, while car engineering is becoming sexy with the interest in hybrid, fuel cell, and intelligent cars, so maybe things will even out more.

I did know an MIT Mech E who went to Ford out of school, but he left relatively quickly. I know a Gatech Mech E who's happily working at Lockheed Martin.

The WTO wants to control what you can eat

Farhad2000 says...

There is a severe misconception when it comes to discussing the World Trade Organization. Very briefly I will try to clear some things about what the WTO does...

The WTO negotiates trade agreements on the global level between governments for trade standards, it succeeded the General Agreement on Trades and Tarrifs (GATT).

Trade is one of the most important factors of economic development, if one country is good at producing one specific item it would trade with another nation that is good at producing something else, both parties benefit in a fruitful trade environment. This is important because trade creates what is called comparative advantages, e.g. Germany is good at producing beer, Russia is good at producing vodka, the both trade to gain benefits. Basically some countries are better at producing goods A and others at goods B, both trade and both expand and benefit as such.

Before the great depression and both World Wars, trade between nations was fairly open, nations would freely allow the movement of goods from one point to another. However post these economic shocks protectionism entered, countries started to close borders and introducing tariffs, import restrictions, quotas and variable import restrictions. This is problematic, some countries would not say have the infrastructure for heavy industry so cannot efficiently produce cars, other countries don't have the labor for cost efficient agricultural development. So there is a economic opportunity cost when investment takes place in industries that the benefit has no basis or advantage in, for example in my country they opened a computer factory during soviet times even though we were so far behind in development and software. There is a waste of scare economic resources then.

With GATT and WTO afterwards it, many of the trade restrictions have fallen the world over, leading to the cases we see of economic development in areas like South East Asia (China, India and the Asian Tiger economies).

However there are problems.

- Both WTO and IMF represent private corporate interests, siding with larger economies over smaller ones, so private interests in Western Nations can dictate the terms to smaller ones.

- Larger players possess the legalese and knowledge to push charges against smaller players, e.g. in the form of dumping charges (country A is dumping goods at below cost of production to penetrate the market to country B). For example the South East Asian economies are commonly accused of dumping their goods to the western world, when in fact its simply comparative advantages such as larger labor poll and such.

- Since trade barriers were existent already, large areas were already protected via political interests, the biggest being agriculture between 1st world and the 3rd world or smaller ones like timber trade between US and Canada.

An organization like the WTO is needed in that its a common form for discussing trade on a global scale, but it does not represent the interests of all fairly or provide a platform for such, one glance of their website will show you how many nations the US accuses of unfair trade advantages because its protections local interests.

However this is illogical, no nation can possess all production assets, due to scarcity, and the global economy is tightening year on year and becoming interdependent, which is a good thing, its very hard to bomb someone if your and theirs economies are connected through trade, this is happening between the US and China.

Its also presentative of the different rearrangement of economies over the long term, take the case of the UK a country that has went from primary industry, secondary and now is almost purely a services economy. China is now the worlds producer of simple secondary goods, the US is now a bigger R&D developer. The third world if it was allowed could feed the whole world and so on and so forth.

The economies are now interdependent as well, take your average laptop, the technology was probably developed in the US and Japan, the semiconductors were made in Malaysia and South Korea, and it was all put together in China.

Its not a perfect system by a long shot, however looking over the ages, economics is far better at leveling the playing field and brining together nations then idealistic statements and or anarchy which is common seen at WTO/IMF/G8 meets.

Of course there is a million other issues to consider... but I said this was a *cough* very brief description.

Intels 80 core processor

dgandhi says...

Besides, there's no evidence that any sentient being is a better designer than evolution.

Umm... Okay, our eyes are wired backwards, our spines and your knees are not efficient for bipedism, our feet are terribly fragile, our brains can't process numerical information as quickly or reliably as a $0.05 microchip.

While I agree with you in a meta sense, as our brains are a product of evolution, and so the products of our brains are as well. I think you underestimate the waste inherent in blind modification/selection. If we have sufficient understanding of a problem to solve it , or even to minimize the problem set to the point that we can use artificial selection, then brains have gotten us there, because that is what brains do well. Look at how quickly technology is evolving, semiconductor logic was nowhere to be seen 100 years ago, evolution can't touch that kind of development speed.
