Nobody argues that the adhesives aren't up to the task of holding the machine together. Just that they make repair and/or upgrade difficult. Obviously Apple deems it worth saving the few cents it would take them to use a more convenient fastener even if it costs them in warranty repair time. Economically they're almost certainly correct, but it still seems like something of a dick move to those few of us who still repair our own machine.

Many of the older iMacs you open with a plunger and/or suction cups -- remove the glass with the suction cups, then unscrew the screen. This sounds worse than it is. This one (and I think the previous one) is held together with tape; you have to use a cutting wheel to cut the tape from the side, then pry it apart. To put it back together you need to remove the tape remnants and put new tape on.

Statistics and Logistics were a major part of my CS degree way back in the late 80's, more so than writing programs. If you think the only place statistics are used in tech companies is in marketing material then I have to conclude you have never worked as a corporate plumber and have no idea what they do. The core reason developers have always attracted good salaries at large corporations is that they can sift through mountains of data and tell the managers something about their business that they didn't know.

I'm not that far from retirement but that job will disappear in the near future, the technology in IBM's Watson will "democratise" data analysis in the same way the PC has "democratised" programming. Experts will have a "conversation" with the computer in which man and machine will both "learn" something, Google style search engines will look as quaint as a "ready reckoner" book of maths tables. And yes, Watson relies heavily on statistics, it doesn't actually give you an "answer" it gives a range of answers with an associated probability. Sounds kinda flakey but the fact that it can beat the world's top trivia buffs in an open ended problem domain is old news.

When it won the Jeopardy championship a few years ago it needed 2 tons of air-conditioning alone and was an exclusive toy for IBM devs. Today it fits on a "pizza box" server and IBM have recently opened the API to the public.

Disclaimer: Worked for IBM in the 90's, not shilling, just my personal opinion that "cognitive computing" may turn out to be more significant to human history than anything else that's happened since WW2.

Earth sciences such as climate science are what is known as a "systems science", the aim is to model the behaviour of a system using accepted physics, chemistry, economic behaviour, etc. That's why technically a climate model produces a "forecast" not a "prediction". Also although we don't have a replica Earth, we do have Venus and Mars, planetary science has taught us a lot about our own planet. Some people complain that it's "just statistics" but they don't seem to mind that temperature and pressure are also "just statistics".

Don't bet on that, Cheerios have a lattice like internal structure that has orders of magnitude more surface area than what it would have with a smooth surface. You're intestines work on the same principle, they are lined with microscopic "fingers" that maximise the surface area used to absorb nutrients, without those fingers you would starve to death in a matter of weeks.

While on the subject there's a good chance that rocks that have an internal structure similar to cheerio are an essential part of the hypothesis that life emerged from volcanic vents on the sea floor. The tiny bubbles in the rocks (think charcoal,scoria,etc) are perfect for forming lipid bubbles - primitive cell membranes that spontaneously arise from the lipids found in clay, clay only forms under water. Volcanic vents are the #1 suspect in the hunt to find where life arose on Earth...interesting stuff, you can google the rest with "abiogenesis Harvard"

Depends what you mean by "welfare", many people on the right of US politics would argue that spending tax money on health and education is welfare. Good governments don't create jobs they create new markets and opportunities via regulation. A wise government equips their people with the tools to recognise and exploit those opportunities in a way that benefits society as a whole.

Lead pollution and abortion may well have some influence, however the reason the US has more prisoners that any other nation is its absurd practice of locking up people for possessing a banned substances. You guys have the highest incarceration rate in the world, higher than oppressive hell holes like Sudan or Saudi Arabia and 7X that of China. In fact in raw numbers the US has almost as many drug war prisoners as the EU has prisoners for ALL crimes.

It a good thing to see the US is finally starting to moderate that socially destructive policy, I hope the numbers continue to drop.
