  1. Ever tried driving on a 6-lane highway that hasn't been painted? It's not easy to stay in lanes that aren't marked. A lineless 6-lane road is good for 4 lanes of traffic.

    As the thread gets finer, so does the mesh. Pressure remains constant when thread diameter and mesh spacing change in sync.

    The problem is that thin chain mail will not distribute impact well, and thickness achieved with multiple layers helps that.

    Space elevator and Low Earth Orbit are not a particularly good match. Most of the energy needed to get into low earth orbit is to gain orbital velocity, the elevator is contributing mostly altitude.

    Space elevator to LEO would work something like this: Vehicle is lifted on the elevator to about 100 miles, detaches from the cable and then uses rocket motors to boost speed by about 15,000 mph -- all without damaging the cable as the vehicle maneuvers rapidly.

    Ceramatec appears to be mostly an R&D company that spins off production entities, but I only looked for about 3 minutes so I could be wrong. Lithium and sodium battery research is ongoing. They focus on ceramics, and a large part of their business is energy related.

    Literally no action a corporation takes is for any purpose but saving or making maximum profit.

    Many corporations, especially small ones, are created to protect the owners from (often frivolous) lawsuits.

    There are also charity corporations.

    Corporations are run by people, and many of those people have motives other than maximizing profit -- the profit is there to make possible the development of their dream.

  11. One of the Gates' contributions is to Common Core. At first glance, CC just seems to be setting national minimums, which might be a good thing. If you look a little deeper, you'll see a flurry of subjects to be covered, almost all of which seem good. It's only when then analysis gets down to practice that real problems appear:
    • __Shallow coverage of major historical figures, heavy attention on politically correct lightweights.
    • __Emphasis on skills for drones rather than underlying concepts.
    • __Crippling mathematical techniques that are neither practical nor teach mathematical principles

    I don't know if the Gates are responsible for the direction CC has taken in addition to it being yet another program that's been hijacked by the educational establishment. In any case, they should not be funding it.

    Your poor grammar makes it difficult to understand what you're trying to say.

    A mind more certainly can be ill. Brain tumors and parasites, bad body chemistry, can all negatively affect brain function. Brain function encompasses nearly all of what we consider to be "mind".

    As just one example, depression is frequently a positive-feedback system -- unhappiness leading to inactivity and bad dietary choices and the generation of bodily chemicals that further deepen unhappiness. Correcting body chemistry may break the cycle. The mind was ill, the chemicals allowed it to be cured.

    you don't get taxed on what you own

    Property tax on house and car. Now that I'm retired, property tax is my single biggest budget item, followed closely by heating a house in New Hampshire. Together, they account for about 40% of my yearly expenditures.

    under no scenario does giving money to a charity increase you income or hide a fucking thing.

    Giving money, no. But there are plenty of scams for giving physical things and claiming a value far in excess of actual cost, resulting in a reduction of income tax more than the cost of the gift.

    You're one of those people who talks in the theatre, disrupting other people who paid good money to get the best experience. Please leave now.

  15. This is not 80% for one theatre chain, it's for three chains.

    Big theatres are a substantial capital investment, modern digital projectors are also not cheap. The set of businesses interested in running a theatre chain and financially able to do so is not large. There are also some economies of scale..

  16. Your post is illogical. "Color of their skin" is something a hotelier can see, "the sexual acts they may or may not partake of" are pure speculation. FWIW, a hotelier can take steps to prevent his property from being trashed.

    Similarly, "the content of their character" is pure speculation unless they announce their intentions (something that only fools and troublemakers are likely to do.)

    "The content of the ads" is a business decision; they don't want to display material that could discourage customers from returning. Content is part of the service they're providing, and they're providing it to anyone who'll pay for it. This is different from your proposed hotelier, who would not be providing service to anyone who'd pay for it.

  17. "Freedom of expression" is far too broad. It would include things like a man removing his clothes and masturbating in front of a group of nuns and small children.

    The primary purpose of freedom of press and speech is to protect a mechanism for limiting government power and abuse. It is the freedom to transmit ideas. Freedom of expression covers a much wider range of activity, too much of which is undeserving of protection.

  18. People with legal access to government secrets sign an agreement acknowledging that they understand and will abide by the laws relevant to those secrets. There are also laws concerning acquiring secrets one is not permitted to acquire.
    Additionally, "free speech" is absence of prior constraint, not absence of repercussions for damage. That covers the theoretical problem.

    On a practical basis, get real. Passing nuclear secrets is attempted murder and an act of war.

  21. Re:Original Metal Detectors Used Vacuum Tubes on The Quest For the Ultimate Vacuum Tube (ieee.org) · · Score: 1

    No. A TWT relies on the velocity of electrons inside the tube and bunches up the electrons. At least a full cycle of the signal has to be present inside the tube at once. If the velocity is about c/10 (I'm guessing this is a reasonable low end) the tube would have to be 150 meters long for a 200 kHz signal.Precision machining is required, so TWTs are expensive.

    Metal detectors operate at frequencies where semiconductors can be extremely efficient -- I'm guessing better than 90% using PWM and LC filtering. There's not much utility in trying for more.
