    To call the natural process of mutation, literally one of the requirements for any genetic evolutionary progress, “deteriorating” is, at best, short sighted. Most mutations do nothing, most of the ones that do something don’t occur in the one sperm that makes it into the ovum, and most of those that do something and make it into the ovum cause an early termination before birth. Some of those that get through all of these hurdles are the ones that cause random genetic variation and increased diversity, without which we actually DO get things like Hemophilia or other sex-linked issues going rampant in any given gene pool. Evolution takes a LONG time to work, but it requires wet and moldable clay to sculpt.

    Teacher who had a 504 here: no, IEPs are covered under the Americans with Disabilities Act, while 504s are under the rehabilitation act. Most importantly, though, 504s are how you get specific, enforceable accommodations for:

    • eyesight difficulties, including colorblindness
    • medical conditions which require that you receive special privileges (unlimited restroom use, nurse access, specific seating/accessibility requirements)
    • Dyslexia, Dysgraphia & Dyscalculia
    • and SO much more
    • most importantly, protections against revealing such disabilities or retaliation against accommodation.


  • Ringwoodite inclusions in a diamond recently (last decade or so) revealed that water exists in equilibrium with the deep mantle, far deeper than previously thought possible. This has completely changed our understanding of the chemistry of the deep interior of the earth.

    Suppose you are trying to determine the concentration of a solution. You could try to boil off the water and figure out how much solid stuff is left over, but what if it’s a mixture, and you just want to know how much, for instance, “Hydrochloric Acid” is in the water. Or, alternatively, some chemicals (such as Hydrochloric acid) evaporate with the water. We need a way to figure out the concentration of this chemical ( we’ll call it “Chemical X”) without trying to pull it out of the solution.

    So, you need to know how much Chemical X is in your solution, but you can’t really easily separate it from the solution. What do you do? You Titrate! You find some other chemical that reacts with Chemical X, so that this new chemical (which we will call Chemical Y) will get instantly destroyed as long as there is still more Chemical X in solution. So, as long as there is more Chemical X in solution, the Chemical Y will get eaten up instantaneously, reacting with Chemical Y.

    Finally, you just need to have some way of detecting whether any Chemical Y exists in the solution, since the moment you see it in solution, you know there’s no more Chemical X to eat it up.

    Now, you titrate: take a specific volume of your sample solution, and add a known concentration of Chemical Y, drop by drop. Once there is any chemical Y left over, you know you have found how much Chemical X was in the solution to start. Congratulations, you now know the concentration of Chemical X in the sample solution.

    I considered that when posting, though the play of prismatic colors which defines the diamond’s unique lustre, in addition to that same tendency toward internal reflection, are both ultimately caused by the extraordinary refractory properties of the crystal structure, and the refracted light coming out of the diamond after internal reflection is the constituent of the “shine”







  • So, compare this contemporary review, which makes it clear (including a quote from Zimmer himself!) that while Zimmer, Djawadi, and others contributed leitmotifs and notes, the majority of composition was Badelt’s. Now consider Zimmer’s website’s description, which invariably paints himself as the main composer of nearly every track, even claiming the title of primary composer, and seems to erase the contributions of Badelt at every opportunity.

    So, I take any claims of Zimmer’s greatness with a giant salt lick. I originally read another source (which I now am unable to locate) that claimed the only thing Zimmer wrote for the DaVinci Code was the main theme motif, much like “He’s a Pirate” for the first pirates movie. I now generally assume that anything excellent “composed” by Zimmer was some other collaborator’s work, Zimmer offered a chord or two, then used his ill-gotten fame to bully the less-famous collaborators to accept the title of second fiddle while Zimmer mimes the Solo in the spotlight.

    Since an observer traveling through space at the speed of light experiences no time from the beginning of their journey until they decelerate (since their 4-velocity vector has non-zero values only in the 3 dimensions of space), photons don’t just arrive precisely when they mean to, from the moment they are emitted, they have already arrived.
