    Space Weather

    The site typically focuses on solar disturbances. We have to monitor the exposure of our sensitive arrays up there. A reconnaissance satellite looks quite a bit like the Hubble space telescope, excepting that it is pointing back down. That 'flip top' lid can cover and protect the optics if/when we needed to put the bird into safe mode.

    ATMOSPHERIC COSMIC RAYS ARE INCREASING: http://spaceweather.com/ Cosmic rays in the stratosphere are intensifying for the 4th year in a row. This finding comes from a campaign of almost weekly high-altitude balloon launches conducted by the students of Earth to Sky Calculus. Since March 2015, there has been a ~13% increase in X-rays and gamma-rays over central California, where the students have launched hundreds of balloons. The grey points in the graph are Earth to Sky balloon data. Overlaid on that time series is a record of neutron monitor data from the Sodankyla Geophysical Observatory in Oulu, Finland. The correlation between the two data sets is impressive, especially considering their wide geographic separation and differing methodologies. Neutron monitors have long been considered a "gold standard" for monitoring cosmic rays on Earth. This shows that our student-built balloons are gathering data of similar quality. Why are cosmic rays increasing? The short answer is "Solar Minimum." Right now, the 11-year solar cycle is plunging into one of the deepest minima of the Space Age. The sun's weakening magnetic field and flagging solar wind are not protecting us as usual from deep-space radiation. Earth to Sky balloon launches in multiple countries and US states show that this is a widespread phenomenon. Cosmic rays are of interest to anyone who flies on airplanes. The International Commission on Radiological Protection has classified pilots as occupational radiation workers because of cosmic ray doses they receive while flying. A recent study by researchers at the Harvard School of Public Health shows that flight attendants face an elevated risk of cancer compared to members of the general population. They listed cosmic rays as one of several risk factors. There are also controversial studies that suggest cosmic rays promote the formation of clouds in the atmosphere; if so, increasing cosmic rays could affect weather and climate. PHYSICS OF AN EXPLODING COSMIC RAY BALLOON: http://spaceweather.com/ On Nov. 14, 2018, the students of Earth to Sky Calculus launched a balloon to measure increasing levels of cosmic rays in the atmosphere. At the apex of the flight, the balloon exploded and the radiation sensors parachuted back to Earth. A video camera on top of the payload recorded the pop:

    Life Line

    A short story in Robert A. Heinlein's future history compendium of short stories. Robert takes two concepts of modern day physics and turns them into the basis for a plausible future. 1. There exists an electronic device called a TDR (time domain reflectometer) with which one can locate a break or an open circuit within several miles of wiring (for example, the wiring harness of a modern jet fighter). It's not magic, but it works very well. 2. In space-time diagrams, the three spatial dimensions are reduced to one along a horizontal, and time is a vertical axis. Penrose diagrams are an example, and they can demonstrate why time has a direction, how time becomes space, and other nifty things. The lines of an object as it progresses through spacetime are called 'world lines' Consider that your birth was a point in spacetime that began your world line. As you grow, that point starts to become wider and begins to travel (either through space, time or both). Your death marks the end point of your world line, and your entire existence then looks like a worm (whose length is determined by your age at death) Now for the money shot; if you are a conducting point in spacetime, there's a way to find the terminus of your world line?

    There's a mathematic function, called the Lorentz transform, that can be used to transfer perspective between frames of reference in relativistic fields (like time). We all probably have heard that time, for example, is perceived differently by observers in different reference frames. e.g. three observers, one at rest in empty space, one at rest on the surface of a planet and one travelling in a space ship. All three of these observers will disagree not only as to the sequence of events that they observe, but also the passage of time watching the events unfold is different for each (they are in different frames). By applying the Lorentz transformation, one can switch between the frames of reference and get valid results. In a way, the Lorentz transformation is a way of 'normalizing' for a specific reference frame; otherwise known as changing one's perspective Likewise, the Meyers Briggs personality assessment not only gives one a better understanding of why and how they think, and who in history has thought similarly, but also provides a way to switch reference frames (or 'see it another way' or change perspective or 'walk a mile in her shoes') in that one can be more understanding of how another person thinks. JVT mentioned this a bit, in the example that the J (judging) type thinks about things temporaly, while the P (perceiving) type arranges things spatially. In this way, both types may arrive at the same conclusions, but via drastically different mechanisms and value assesments. I guess what I'm hinting at is, if you need or care to communicate effectively with others (remember "Hell is other people"?) some framework similar to Myers Briggs is very helpful in helping individuals understand each other's thought process.

    Two differing models at play; Myers Briggs is based on Carl Jung, and Kiersey is based on Myers Briggs

    You are probably thinking of the Kiersey types; also a popular character map, slightly different than myers briggs
