Biola University’s Prof. Matt Weathers with an umbralarious Easter vacation send-off for his Nature of Math class.
Already knew I was dumber than the fifth graders… but now it’s the pre-schoolers??
A PRE-SCHOOL TEST FOR YOU
Which way is the bus below traveling? To the left or to the right?
Can’t make up your mind? Look carefully at the picture again.
Still don’t know?
Pre-schoolers all over the United States were shown this picture and asked the same question. Click on the link below to see what answer 90% of the pre-schooler’s gave.
Why 1 is one and 2 is two and 3 is three…
The numbers we all use (1, 2, 3, 4, etc.) are known as “Arabic” numbers to distinguish them from the “Roman Numerals” (I, II, III, IV, V, VI, etc). Actually the Arabs popularized these numbers but they were originally used by the early Phonecian traders to count and keep track of their trading accounts.
Have you ever thought why …….. 1 means “one”, and 2 means “two”? The Roman Numerals are easy to understand but what was the logic behind the Phonecian numbers?
It’s all about angles !
It’s the number of angles. If one writes the numbers down (see below) on a piece of paper in their older forms, one quickly sees why. I have marked the angles with “o”s.
No 1 has one angle.
No 2 has two angles.
No 3 has three angles. etc.
…..
and “O” has no angles
