Hello my dearest puzzle solvers. Solve it Sunday is a weekly riddle or puzzle I give to you guys to solve. Each of the puzzles were created by Einstein himself, but with a bit of logic regular people can solve them too.
Today’s puzzle only requires you to think a little bit and read carefully. As always, best of luck to you, and the answers are in the comments!
Although we are 93 million miles from the sun, light travels so swiftly that it takes just eight minutes for its light to reach our Earth. To give you an idea about the vastness of our solar system, it takes sunlight 43 minutes to reach Jupiter, one up to nearly seven hours to get out to poor Pluto. But for now, return your thoughts to this planet.
For the sake of argument, let us pretend that where you are right now, sunrise tomorrow will occur at exactly 6 a.m. However, some unknowable force interferes overnight, so that the light of the sun reaches the East almost instantly. Perhaps a wondrous portal opens that effectively cuts the travel distance of the light down to under a second. The precise mechanism does not matter. What is important is that the light's journey is shortened from eight minutes to fractions of a second, without any ill effect to us.
What time would you then expect to see tomorrow's dawn?
Hello my dear Sherlocks, Einsteins, and other puzzle solvers. You’re probably all cooped up and sick of your family at this point, and need something to keep morale up.
Well, I got just the thing for you.
As always, the solution to the riddle is in the comments.
The mathematics of infinity can be startlingly beautiful. It can allso be just plain startling.
Consider the natural numbers – 1, 2, 3, 4, etc. They are infinite; any number you can conceive of can be increased. Now consider the even natural numbers – 2, 4, 6, 8, etc. These also obviously extend to infinity.
So if you compare the set of all natural numbers with the set of all even natural numbers, which is larger?
My dearest Einsteins, Holmes, and whatever other smart people you might think of. Solve it Sunday gives you puzzles and riddles from a book called Einstein’s Puzzle Universe, and gives you the chance to solve it using those brilliant minds I know you all possess.
Some are more difficult than others, but they all require a bit of logic.
Here’s this weeks’ puzzle:
The puzzle below holds a well-known quotation. Although the words in each line remain in the correct order, all punctuation has been removed and the lines themselves have been jumbled up. Are you able to piece the original quotation back together?

Hello my Little Einsteins, I hope you have your thinking caps on. Today’s puzzle is all about windows, which really doesn’t make a difference for a genius like you!
And as always…answers are in the comments.
Imagine that you have a square window, five feet high, set in an opaque wall. That window lets in a certain amount of the available light outside. Simple.
It is possible to modify the window to precisely halve the amount of light that it lets in without changing the type of glass, placing a curtain, filter, or any other sort of obstruction over the window or between the window and the viewer — while still keeping the window square, and five feet high.
Hello everybody, I hope you have your thinking caps on! I’m back for another Solve it Sunday post, and this week is a tricky one.
As always, answer is in the comments, and you think you have the right answer, make a comment of your own.
During the 19th century, a European colonel in Ethiopia recorded a report of an encounter with local tribesmen, from whom he was purchasing cattle.
He wanted seven beasts, at a cost of 22 birr each. Not being numerate, the herder called a local priest to verify the total price.
When he arrived, the priest dug two parallel columns of holes. The right-hand column represented the purchase price, so in the first hole he placed 22 stones, and then halved the number of stones for each subsequent hole, rounding down. This gave him 22, 11, 5, 2 and 1 stone.
The left-hand column then represented the cattle, and in the first hole he placed seven small stones. He then doubled the number of stones for each subsequent hole in the column, so that the holes contained 7, 14, 28, and 112 stones.
Declaring even values to be evil, the priest then went down to the right-hand column and whenever he encountered an even number of stones – the 22 and 2 holes, in this instance – he removed the stones from that hole and its neighbor in the left-hand column – 14, 28, and 112 respectively – into one pile, which he counted out one by one.
They came to 154 birr, which was indeed 22×7.
Indeed, this technique of multiplication will always work for whole numbers, but why?
