Things I learned lately - 12 August


  • In September, Google Chrome (53) will start blocking Adobe Flash.
  • On 4 Aug 2016, a sun-grazing comet slammed into the sun at a speed of 600 km per second, or 2.16 million km/h.
  • If you're watching a recorded show on your PVR (at least here in Calgary), and a weather emergency notification is broadcast, you'll see it, even though you're not watching live TV. (They were warning of a possible tornado)
  • Technically, Jupiter doesn't exactly orbit the sun. In other words, it doesn't orbit the centre of the sun's mass, it orbits the combined centre of gravity, which is above the sun's surface. So the orbit is more like a dance, where the sun wobbles around that centre of gravity and Jupiter orbits it too, but from much farther out.
  • The Solar Impulse aircraft successfully travelled around the world, 40,000 km, without using any fossil fuels.
  • Rhubarb has been used in Chinese medicine for thousands of years.
  • Only 5% of all the African slaves brought to the Americas went to the US.
