At a weekend conference, the digital piano was in fact electronic piano. I don’t know whether people make that difference (digital or electronic) or whether the naming system is consistent across manufacturers. Briefly, digital piano has better sounds (and more effects) than electronic. It sounds like a major difference, but some of it is due to very small margin in design. On small margins, human can only survive in small margins of temperature. I read that scientists discovered a planet a few years ago which they named GJ1214b. They worked out this planet is made much more of water than […]

No longer in its teenage years, in early 2019, it had reached a point in space no human created object had travelled to, and transmitted back images of a planet it sought to focus on – Ultima Thule. Thinking about this a month after the event feels like a long past event, historical. But scientists had planned for this several human generations ago; to some, even the launch was before they were born. Human creativity and capacity in science is phenomenal. As someone completely uninformed about planetary science, I’m sure much of the […]
