- Scientists have made a step forward in their ability to mimic the sense of touch. A team from the US and China made an experimental array that can sense pressure in the same range as the human fingertip. The advance could speed the development of smarter artificial skin capable of “feeling” activity on the surface. The sensors, which are described in Science magazine, could also help give robots a more adaptive sense of touch. Using bundles of vertical zinc oxide nanowires, the researchers built arrays consisting of about 8,000 transistors. Continue reading the main story. This is a fundamentally new technology that allows us to control electronic devices directly using mechanical agitation. Each of the transistors can independently produce an electronic signal when placed under mechanical strain.

Many students gone here and there. You are going to have to do a lot on your own to get caught back up. Hopefully, this website will help.

- Red marker shows Tycho’s island
-
- Tycho built the castle and observatory Uraniborg on Hven in 1576 (with a laboratory for his alchemical experiments in its cellar) and then Stjerneborg nearby in 1581. Unusual for the time, Tycho established Uraniborg as a research centre, where almost 100 students and artisans worked from 1576 to 1597.[

- Mar’s apparent Retrograde motion if you are using the Ptolemic system. This required early 16th century Ptolemic astronomers to add epicycles (circles within circles) to planet’s orbits.

- Kepler’s museum in Prague. Not nearly impressive as it should be considering he changed mankind’s view of the solar system.

![The Kepler observatory is "specifically designed to survey a portion of our region of the Milky Way galaxy to discover dozens of Earth-size planets in or near the habitable zone and determine how many of the billions of stars in our galaxy have such planets".[7] A photometer continually monitors the brightness of over 145,000 main sequence stars in a fixed field of view.[8] This data is transmitted to Earth, then analyzed to detect periodic dimming caused by extrasolar planets that cross in front of their host star.
