Science News – Do Black Holes Exist?
For years black holes have captured the imagination of the public as well as physicists, featuring heavily in science-fiction books and films. But now it seems that they may not exist after all.
Is The Great Wall of China Visible from Space?
The idea that the Great Wall of China can be seen from space has been around since at least 1938 and is still popular today. It certainly seems plausible that such a large, linear structure would stand out from the surrounding landscape, but it’s actually not true.
Alan Bean, the fourth man to walk on the moon, said in 1969
“The only thing you can see from the moon is a beautiful sphere, mostly white, some blue and patches of yellow, and every once in a while some green vegetation. No man-made object is visible at this scale.”
But if you can’t see the Wall from the moon, how about somewhere closer to Earth? The International Space Station (ISS) maintains a low earth orbit of between 330-435 km above our planet’s surface.
Unsung Heroes – Lollipop Men and Women
Is there a Lollipop Man or Woman on your road to school? Do you know his or her name?
When I take my children to school, we walk if we can, because the parking situation near the school is a bit difficult. On our way we cross the road where the Lollipop Man stands guard.
He isn’t particularly talkative, but is friendly and helpful. It has been warm these past days, and still he stands, in his reflective jacket and ear-muffed reflective hat. I am waiting for him to take the hat off, he must be sweltering under there. Perhaps he has a lighter hat in his cupboard, which doesn’t get worn until summer.

I fell off, honest
Learning to ride is a fabulous hobby. It can be pricey, but you can borrow a hat and crop from most stables, and start off in trousers and strong shoes. It is great exercise, very exciting, and teaches respect for animals, balance, and correct posture.
When I was very young I rode at Stourton Stables, a children’s riding school where the ponies were mostly grumpy and had to be separated in the fields for fear of kicking each other to pieces.
Oh, happy riding lesson days. Hours spent in icy pouring rain, in snow, in fog, and even more rarely; in lovely sunshine. The best riding times of year for me were spring and autumn, before and after the major insect season.
