Integrated Circuit Is 50 Years Old Today 117

arcticstoat writes "Today marks fifty years since the first integrated circuit, or microchip, was demonstrated by Jack Kilby at Texas Instruments on 12 September 1958. The original chip might not be much to look at, but then Texas Instruments admits that Kilby often remarked that if he'd known he'd be showing the first working integrated circuit for the next 40-plus years, he would've 'prettied it up a little.' The integrated circuit itself was housed in a germanium strip on a glass slide, and it measured 7/16in by 1/16in. With protruding wires, and just containing a single transistor, some resistors and a capacitor, it's a primitive chip by today's standards, but it worked and successfully produced a sine wave on an oscilloscope screen at the demo. Technology hasn't been the same since."

      Yeah, but they fail to account for the fact that correlation != causation. Technology's been moving along at a fairly rapid pace since the 1800s; perhaps it's just a coincidence that integrated circuits came along around the same time electronics started taking off.

        You're right. Correlation isn't causation. But correlation is nevertheless good EVIDENCE of causation. I'm sick and tired of people parroting "correlation is not causation" every time a correlation is used as evidence for causation.

          Indeed!

          I'd add that correlation usually implies that there is some common cause which is a necessary condition of all the correlated events, even if it is not sufficient to cause all of them by itself.

          People frequently loose sight of the fact that all "correlation != causation" is meant to indicate is that the common cause of correlated events is not required to be one the events themselves, but can be some other external event.

          First of all, it was a joke, come on people.

          Secondly, correlation is pretty bad evidence of causation without something else backing it up. Correlations happen all the time for many reasons. There are many orders of magnitude more good correlations than there are causal relationships.
          • Something else to back it up like another correlation?

            How can you determine the cause of *anything* without a correlation?

            It's just that some correlations have more/fewer variables to take into account to determine how much support it should have for a cause.

              How about an analysis of those variables that have to be taken into account? That's a good way to back up a correlation that isn't in and of itself another correlation. There's experimentation. That's useful. Logic works too. In the case of IC, we can directly trace the history of electronics and determine that IC played a very large part in it.

              Correlations can be used as supporting evidence, but they're weak to the point of ridicule by themselves. I can't believe this is even an argument on a forum of educated people. The scientific method, at its core, is a method used to remove the uncertainty from correlations in the data so that you can say with confidence that either the correlation in the data is a cause and effect relationship or that the experiment was set up improperly. Perhaps, instead of bitching about correlation not being accepted as evidence of causation, you should praise people for having the skepticism that's driven the scientific revolution of the past few centuries.
          • First of all, it was a joke, come on people.

            Oooooh, I see. Was it a good joke?

    For a laugh and some historical perspective, dig out the datasheet for a 555 timer. It's an ancient chip by any standards, but still extant. The designers were obviously rather proud of how many transistors this chip could replace (something like 25), and the datasheet is clearly bragging about this. In a modern context, this is pretty funny. Of course, designing a chip with that kind of lifespan is braggable.

      There are no patents on the 555. Signetics did not want to apply for a patent. You see, the situation with patents in Silicon Valley in 1970 was entirely different than it is now. Everybody was stealing from everybody else. I designed the 555 Signetics produced it, and six months, or before a year later, National had it, Fairchild had it, and nobody paid any attention to patents. The people at Signetics told me they didn't want to apply for a patent, because what would happen if they tried to enforce that patent, is the people from Fairchild would come back with a Manhattan-sized telephone book and say "These are our patents, now let's see what you're violating".

    I was debating a coworker about the greatest invention of the 20th century, we both agreed that the miniskirt ranks higher than the transistor. It's interesting that they both came out around the same time.

    • While I would not be inclined to disagree, it is worth noting that possibly the most daunting conundrum facing humanity for the twenty first century is the fact that while the number of transistors packed into an IC is approaching infinity, the annual reduction in miniskirt lengths is rapidly approaching zero; we are in desperate need of a global miniskirt paradigm shift to offset this most disturbing reality.
