    Uppercase upsilon looks like the Latin uppercase Y - which is just the Y we use in our alphabet. Lowercase gamma looks similar (but not exactly like) to our lowercase y. Uppercase gamma looks like a vertically flipped L, and lowercase upsilon looks similar (also not exactly) to our lowercase u. Though then this can get easily confused with lowercase mu or nu... it's tricky.

    Wonderful video, thank you, it IS gamma, however, you were also calling it upsilon (the 20th letter of the a.grk. alphabet), not epsilon (5th letter). Epsilon looks like a cursive e, but upsilon looks like a u, and capital upsilon looks exactly like Y, hence the confusion. In French, y = "i-grèque" whereas the french u is more akin to the "oopsilon" pronunciation of upsilon (English we should just say uh-psilon). Different from epslion. Language doesn't make sense.
