  • Once upon a time, air travel was the purview of the rich and famous. Early aviators like Amelia Earhart were celebrities, but their once-dangerous routes are now flown hundreds of times a day by commercial jets that most people can afford to fly on. The reason we all fly around today is that aviators discovered a virtuous cycle of scale -> profit -> investment -> scale that enabled the industry to develop ever larger and ever more efficient aircraft.

    The same thing is going to happen with Spaceflight over the next few years. It took us about 60 years, but we have finally reached the point where lots of ventures can make profits in space, which should hopefully trigger another virtuous cycle that will end with affordable space travel for all



  • Something that some of the other replies have missed is that older movies were often shot (and a lot of actors were trained) from the perspective of a “stage play for the silver screen.” Stage plays have to work for large audiences, and so they tend to feature more exaggerated voice / body movements. These tricks were used on movies for a long time, but have faded as visual effects and sound recording have gotten better




  • The degradation of TV audio was inevitable once flatscreen monitors started to get really thin and big. We now sit farther than ever from our screens, which leads to higher pitched dialog getting quieter (since it attenuates faster than low pitched sounds - think about how you can hear a car stereo from around the block, but can’t hear your neighbor’s baby crying). In addition, our quest to eliminate speaker grills has led to designs that either point speakers straight down (obviously bad), or use complex sound piping to reorient sound through small openings (sorta bad).

    When you add in the fact that most TV and films are now designed explicitly for surround sound and/or good headphones, you can imagine how bad things get for most people.





  • Hi Tmpod! This is actually a common misconception among the general device-using public!

    You are absolutely correct that a lithium battery will degrade if you maintain a state of charge (“SOC”) for long periods of time that is either above 90% or below 10%. Of course, phone manufacturers know this too, and they have set the charging software to block off the top of the pack, which allows the user to safely leave their phone on the charger indefinitely.
