The chemical party

Ken Perrott Sep 16, 2015

Just imagine teaching chemistry this way. I guess you would have to lay off the juice, though. Otherwise, there could be some impossible bonding – and student recall would be low. Thanks to: Sciencegasm shared Universitetet i Oslo (UiO)’s video. Similar articles … Read More

A job with a view – but not for the clumsy

Ken Perrott Sep 15, 2015

Here is a breathtaking GoPro video of a spacewalk by two Russian cosmonauts, Mikhail Korniyenko and the record-breaking Gennady Padalka, outside the International Space Station (ISS). (Padalka recently set a new record of 879 cumulative days spent in space.) It is certainly an exciting job – and what a view! But I’m amazed at all the fiddly stuff … Read More

Credit: Warwick Smith/ Fairfax NZ Apparently a source of “fluoride-free” water provided by the Palmerston North City Council since last May has seen little use.

The list is from the article  5 simple chemistry facts that everyone should understand before talking about science posted on the blog The Logic of Science.

Humanitarian intervention but when & how?

Ken Perrott Sep 07, 2015

People are demanding politicians do something about the current refugee crisis. They are demanding humanitarian intervention, a change in the normal rules and so that refugees can be settled safely. Politicians are dragging their feet – which is inhumane, considering the gravity of the situation. But I do have sympathy for the view, expressed by some politicians, that this sort … Read More

Discussing science on social media

Ken Perrott Sep 03, 2015

Some relevant memes I picked up on Facebook recently. How often do discussion partners adopt this approach?: Or when pushed for their “evidence” we have to respond with: Finally, a citation from their recommended “scientific” source – but: Then – the “nuclear” or Mutually Assured Destruction  (MAD) approach  – scientists can’t be trusted anyway: … Read More

In particular how census forms pose the religion question on census forms is posed.   I discussed the problems in my article Non religious in Australia and New Zealand. The Australian census form buried the “no religion” option – and may, therefore, … Read More
