Sunday Science 2

Welcome again to weekend science. A rather exciting paper was published this week: large deposits of water ice have been found in several locations on Mars. Scientists have been eager for results of this kind for decades, but why? What is the significance of finding water on Mars? It gives clues to the geological history... Continue Reading →

Sunday Science 1

This week in biotechnology: glowing plants! Scientists have been working on making glowing plants as early as the 1980s. Mostly, this has involved using genes from the firefly or a bioluminescent bacterium, with little real success. The latest development was by chemists. Instead of genetic modification, chemists used chemicals; luciferase, an enzyme from the firefly,... Continue Reading →

The day before the article, I'll briefly talk about some scientific background. Welcome to the first Saturday Science! Today, we're going to talk about biotechnology, and tomorrow will...

Xi’an

Xi'an was another city that we visited for one reason: the Terracotta Army. There are 3 main excavation sites, but most of the excavation has been done in the first one. The other two were dimly lit and most of the soldiers are still entombed. So these photos are from Pit 1. This was, by... Continue Reading →

Luoyang

We went to Luoyang for one thing: the Longmen grottoes. They were more my friend's idea than mine, but I'm very glad we went. The grottoes are limestone hillsides, carved so that buddhas remain behind in the caves. The task was started during the Wei dynasty in the 5th century, and continued until the Tang...

It has plenty to do if you live there, it's mostly well laid out, and it has less smog than Beijing. We... Continue Reading →

Beijing: Day 3

So, I mentioned before when talking about The Forbidden City that I really like the colourful architecture in China. Well, I got to see even more of it when we visited Temple of Heaven. The Temple of Heaven is where the Emperor of China used to do important religious rituals. Ancient Chinese emperors certainly weren't... Continue Reading →

Beijing: Day 2

Of course, if you make it to China, one of the things you should find a way to see is "The Great Wall". A few points you should know first: It is not a single wall, and never has been. Most sections of the wall are in the North-East of China. Parts of the wall... Continue Reading →

Beijing: Day 1

First day, and straight into the sightseeing! On day one, we saw Tiananmen Square and Th Forbidden City. Tiananmen Square was just a square. It does have a long and interesting history of being at the centre of Chinese politics, but that's not something that you can really see when you're there (unless you count... Continue Reading →
