It’s a hot topic because a math professor at Oxford University introduced the story of her 7-year-old daughter’s math homework.
The protagonist of the story is Professor Kit Yeates, author of’Power to Think with Mathematics’, who received a Ph.
The Daily Mail reported on the 26th (local time) that Professor Yeats posted a problem on Twitter on the 24th (Korean time) saying, “Please help my daughter with the homework she received on Monday.”
According to the Daily Mail, the problem he posted was to put a picture of a semicircle and answer whether the proposition’there are two right angles here’ is true or false.
Professor Yeats said, “It’s not a joke. I don’t know what answer to give to my daughter,” he said. “A daughter I know is the first time asking about angles.”
Netizens who saw the tweet gave various answers. Most of them said’True’. Some also said it was’false’.
Their logic is that the radius and tangent of the sphere meet vertically, so the two are correct. However, he also said that in order to explain this process to a 7-year-old daughter, it is necessary to talk about differentiation. For this reason, some netizens criticized “Who is giving this homework to 7 years old?”
But the correct answer was’false’. It was intended to show that there was no right angle through the curved circle.
Yeats said, “I’m going to ask next week’s college math sophomores what they think.”
