The We(s)t Coast - Physics Stop

Marcus Wilson Dec 23, 2009

Back online briefly - blogging is a bit tricky from campsites - not all of them have wireless broadband connections yet - particularly on the West Coast.For those non-New Zealanders, 'West Coast' refers to the west coast of the South Island, which I have now driven the length of. Or as much as is accessible by road, anyway. Having done … Read More

The final frontier - Physics Stop

Marcus Wilson Nov 24, 2009

New Zealand is, hopefully, just a few days away from becoming a space-nation. The private company Rocket Lab  (what a great name - I like names that describe what a business actually does) aims to put up its Atea-1 rocket from Great Mercury Island sometime around November 30th. The payload will reach an altitude of 120 km before returning to … Read More

I hate thunderstorms - Physics Stop

Marcus Wilson Sep 30, 2009

The speed of sound in air is about 330 metres per second (which means it takes  three seconds to go one kilometre). So count the seconds between the lightning and the thunder, divide by three, and you have approximately your range from the lightning in kilometres. (Divide by five for miles). So, the lightning that struck about 4pm yesterday, which … Read More

Climate engineering - Physics Stop

Marcus Wilson Sep 28, 2009

So PhysicsWorld has done a nice article on some of the 'engineering' solutions that might be available for tackling global warming.Generally they are pretty ambitious global-scale plans to turn down the thermostat a bit, given the premise that either carbon dioxide emissions will not fall sufficiently or that, even if they did, the earth would still be too hot and something else … Read More

The greenhouse effect - Physics Stop

Marcus Wilson Sep 25, 2009

I've been reading in PhysicsWorld about some grand ideas for controlling the earth's climate by engineering on a global scale. Some sound pretty fanciful, though some might be just plausible. But before I get there (which will probably be another entry) I think it's worthwhile reminding you what the greenhouse effect actually is. As in, why is it a … Read More

Fog - Physics Stop

Marcus Wilson Sep 08, 2009

Well, what does one expect living in Waikato? Four days of gorgeous spring weather in a row is a bit much to ask for. So the fog was back this morning, and with it the idiot car drivers who don't put their lights on. Why? Do they want to die? A white car with no lights in fog is really … Read More
