A few years ago Apple Maps were slammed for some rather improbable image renderings - bridges that appeared to melt into channels, melted highways and so on. The same happens with Google Earth. Nice examples of edge conditions for the software..
Forget about the Tesla Model 3 for a moment. Sandy Munro, principal at the legendary automobile fabrication cost analysis firm of Munro & Associates on their tear-down of the BMW i3. The i3 is held by many as the leading edge of automobile fabrication - way beyond everyone else. The link with a more information on the teardown here as well as how to get the $500k ten part report.
Women in science, math, engineering, or technology have a hard time at just about every level of hiring for academic positions, due to the unconscious bias of those who do the hiring. There's overt sexism, like that awful peer reviewer who said women researchers should get help from men, and subtler forms, like how male researchers tend to choose fewer female trainees to work in their labs. And the STEM bias starts as early as grade school.
This usually isn't because people intentionally discriminate against women and girls. Harvard has a fascinating research project that tries to measure unconscious biases. You may believe with all your heart that women and men are equally capable at science or math, Harvard's researchers say, but your automatic associations may show otherwise. This explains how even a feminist science teacher who knows she is being observed can still give a disproportionate amount of talking time to the white male students in her classroom.
Pao argued in November that the low numbers of women in technology fields isn't just a "pipeline problem" caused by lack of interest among women. The problem is that women are treated badly at every level of entry to these fields. One study found that an uncivil workplace culture systematically pushes women out of engineering fields. While 20 percent of engineering graduates are women, just 11 percent of all engineers are women.
Missions to the outer solar system have had spectacular science returns. The spacecraft are engineering marvels, but the behind the scenes of how missions are proposed and chosen is rarely published. Here's a bit on New Horizons - the mission to Pluto and beyond.
By many measures the carbon fibre BMW i3 is the most sophisticated car in the world. For those that like to watch the manufacturing process a series of videos (you can find the others easily). Very little narration and probably uninteresting to most, but lots of 'my gosh' moments.
Some counterfeit chargers are really risky... too simple for the task and poorly constructed without regard for safety of person or profit. Usually these have dramatic cosmetic flaws that are obvious. Ken found a bad one that looks ok on the surface.
