It is so creative to use math to show the concept of converge. I have been interested in math all my life, so I took a few minutes to verify the accuracy of the formula in your post.
For alternative additions and subtractions, the left side of the formula can be simplified as (3/4 + 3/16 + 3/64 + …….). Then move entire left side over to the right side of the formula, which becomes 1 – (3/4 + 3/16 + 3/64 + …….). Step by step, it will become (1/4 – 3/16 – 3/64 – …..), then (1/16 – 3/64 – …..), then (1/64 – …..). Following the same sequence, it will become a 1/(multiples of 4), i.e., an inverse of an infinite number, which should be zero.
This gives the verification of the equation.
Am I right?

Hi, Yan,
Sorry for the delayed reply! Here’s my take on it (it’s a JPG image: click on it to see a larger version)—

Probably 75% of all the pictures I take are towards a vanishing point, what is being called convergence here. Yours are lovely :-)

Excellent interpretation of this week’s challenge. You took me right back to my school days with the math…which I seem to have forgotten how to work out with formulas :)
LikeLike
You may not have studied infinite series. They open up a can of worms, and so are usually studies fairly late…
LikeLike
Actually, now that you say it, I might have come across infinite series during my university days. I think when you talk about infinite series, you study things like limits, geometric series, absolute convergence… I’m more of a creative kind of person, shying away from numbers… :)

That sounds about right.
Of course, mathematicians would say—and I agree—that mathematics is very creative, since it creates a whole abstract world ;-)

amazing! why do these pictures make a curve in the distance?
LikeLike
That’s a very good question, and the answer is not immediately obvious. But some back-of-the-envelope ray tracing suggests that it’s probably because the two mutually reflecting mirrors are not set into their respective walls exactly parallel to each other, or are themselves a bit curved.

Unfortunately, the formula is not equivalent to the photos in any precise way, so the photos don’t provide an illustration of the mathematics…
