Today, I learned about:

Exactly four years have gone since I wrote my first post in this blog, 2016-01-09. It was really short, talking about potatoes, but it gave me the kick to want more. The story about why I started the blog was published on 2017-01-14.

Thank you all who follow my blog and write me with suggestions about what to publish in future posts!

A hint to ‘Can you use an hourglass’?

In my most recent post, on 2019-12-31 , I gave you a problem involving the use of two different hourglasses, with capacity of 11 min and 7 min, respectively, and asked you to measure exactly 15 min.

If you are still fighting with the solution, let me give you two important hints:

11 – 7 = 4

and

15 – 11 = 4

Can you solve it now?

A complete solution will be presented in my next post.

That’s what I learned in school !
