  • Rightness is a prison

    choices that really do matter to us are often circumscribed by a need to defend our past decisions. We might stay in a bad relationship we know we need to leave, cling to a house that’s a bad investment, or hold onto an ideology that doesn't fit the facts, all because we confuse changing our minds with losing our dignity. When you learn to admit that you’re wrong, you also learn to course-correct much faster. You’re not committed to the decisions of the you who existed yesterday, who had much less information than the you of today.

  • Performative virtue-signaling has become a threat to higher ed

    We asked: Have you ever pretended to hold more progressive views than you truly endorse to succeed socially or academically? An astounding 88 percent said yes. These students were not cynical, but adaptive. In a campus environment where grades, leadership, and peer belonging often hinge on fluency in performative morality, young adults quickly learn to rehearse what is safe. The result is not conviction but compliance. And beneath that compliance, something vital is lost.

  • passive microwave repeaters

    For the telephone industry's many small players, and even the more rural Bell Operating Companies, another property of microwave became critical: with a little engineering, you can bounce it off of a mirror.

    In 1956, James Kreitzberg moved to Salem and the two brothers formed the Microflect Company. From the sidelines of McNary Field, Microflect built aluminum "billboards" that can still be found on mountain passes and forested slopes throughout the western United States, and in many other parts of the world where mountainous terrain, adverse weather, and limited utilities made the construction of active repeaters impractical.

    In practice, a passive repeater functions a bit like an active repeater that collects a signal with a large antenna and then reemits it with a smaller directional antenna. To be quite honest, I still find it a bit challenging to intuit this effect, but the mathematics bear it out as well. Interestingly, the effect only occurs when the passive repeater is far enough from either terminal so as to be usefully approximated as a point source. Microflect refers to this as the far field condition. When the passive repeater is very close to one of the active sites, within the near field, it is more effective to consider the passive repeater as part of the transmitting antenna itself, and disregard it for path loss calculations.

  • Pre-Sputnik Earth-Orbit Glints - by Robin Hanson

    The First Palomar Sky Survey, using the 48-inch Schmidt telescope at Mount Palomar 1949-1958, was the first comprehensive photo survey of the entire northern sky. It took almost 2,000 square photos, each covering about 6° on a side. Typically, each region was photographed twice in a row, once using a plate sensitive to red light for ~50 min, and then one sensitive to blue for ~10 min. These plates were later digitized, and recently the VASCO project has looked for “transients”, i.e., objects seen in the red but not blue plates. For example, three close transients appear in the middle of the left plate but don’t appear in the right. And, as usual, they are never seen by any later telescopes. We have good reasons to think most of these transients are brief glints of sunlight off of flat reflective objects in the rough ballpark of Earth GEO, as opposed to being defects in the photo plates, self-illuminating sources like stars, or sources much closer or further.

    These glints also seem to have a significant date correlations with nuclear tests and UFO reports. Glints were 45% more likely (p = 0.008) on dates within one day of nuclear tests, and there was a significant (p<.001) correlation between the number of UFOs reported and number of glints on each date. In fact the cluster of three close glints above appeared on July 19, 1952, during one of the most famous UFO events of the era at Washington DC. (They were 2km apart if at GEO.)

    it seems we must take seriously the claim that these were glints off of big flat reflective parts of advanced devices from an alien civilization. That kinda hurts to type, knowing that many of you will respect me less for saying so. But I gotta go where the evidence leads.

  • The reason the West is warmongering against China

    capitalists in the core states are now desperate to do something to restore their access to cheap labour and resources. One option – increasingly promoted by the Western business press – is to relocate industrial production to other parts of Asia where wages are cheaper. But this is costly in terms of lost production, the need to find new staff, and other supply chain disruptions. The other option is to force Chinese wages back down. Hence, the attempts by the United States to undermine the Chinese government and destabilise the Chinese economy – including through economic warfare and the constant threat of military escalation. Ironically, Western governments sometimes justify their opposition to China on the grounds that China’s exports are too cheap.
