Generalist to specialist - FutureworkNZ

Guest Author Dec 05, 2019

Amelia Sharman Both my parents are pretty handy – and they seem to have the right tools for most jobs in the garage and they know how to fix practically anything. A similar story could be told about their generation’s experience in the workforce – being a generalist was not unusual and turning your hand to most activities within … Read More

Bite-sized learning - FutureworkNZ

Guest Author Dec 03, 2019

Amelia Sharman There’s no one-size-fits-all when it comes to micro-credentials, those bits of bite-sized learning that can help workers stay on top of technological change.  What’s a micro-credential? While definitions vary, micro-credentials can be understood as short courses that allow people to learn new skills or have an existing competency recognised. The important thing is that at the end … Read More

Among my favourite asteroids: (2309) Mr. Spock - Out of Space

Duncan Steel Nov 27, 2019

Minor planet/asteroid (2309) Mr. Spock is named not for the character in Star Trek, but for a cat that was itself imperturbable, logical, intelligent and had pointed ears.  In a preceding blog post I introduced one of my favourite asteroids, (2472) Bradman, and also mentioned (6581) Sobers amongst a few others. I did have something to do with the … Read More

Among my favourite asteroids: (2472) Bradman - Out of Space

Duncan Steel Nov 25, 2019

There are many thousands of asteroids with formal names, some humdrum but other more noteworthy (depending on your predilections). One of my favourites, the name of which I was involved in suggesting, is (2472) Bradman, named for the Australian cricketing great. After discussing (2472) Bradman, I also make some comments about (6581) Sobers.  As a minor planet (synonym: asteroid) spotter, … Read More

JFK’s assassination: a bit of physics - Out of Space

Duncan Steel Nov 22, 2019

There are perennial arguments about the circumstances of the assassination of President Kennedy in 1963, and in particular whether more than one shooter is required by the evidence (such as the Zapruder film). Those who know little about physics frequently claim that the sharp backwards motion of JFK’s head as the fatal shot hit him is proof that there must … Read More

Earth’s artificial rings - Out of Space

Duncan Steel Nov 20, 2019

Satellites pass over NZ all the time (literally). Here I focus on the 187 Planet Labs ‘Dove’ Earth-imaging satellites, and I show that one can determine in advance where they will be, enabling scientists on the ground to correlate their environmental and other data collection with opportunities to get imaging from space. That is, we can get ‘space-truth’ (rather than … Read More

How NZ was put on world maps using a transit of Mercury - Out of Space

Duncan Steel Nov 10, 2019

There will be a transit of Mercury – the planet Mercury will pass across the face of the Sun – taking place at sunrise in New Zealand on Tuesday, 12th November. It was by observing such an event 250 years ago that James Cook and his scientist colleagues were able to determine the longitude of NZ, and so put these … Read More

India a major player in Earth observation satellites - Out of Space

Duncan Steel Oct 15, 2019

While many imagine that countries like the USA and Europe dominate space activities, in fact India is now a major player on this stage. It launches satellites for its own purposes and also commercially, and has constellations orbiting our planet and returning data of vital importance to that nation in many ways.  Yesterday I was really pleased to give a … Read More
