Chibi professor

Megan is really into Japanese culture and likes to draw manga (Japenese cartoons). One style of cartoon drawing is called Chibi, which is a style where characters look short and cute.

Since Albert has always liked drawing cartoons, he decided to add a little interested to his math and physics classes. He made a few extra credit questions and learned how to draw chibi characters.

And since he’s an engineer, of course he had to use an appropriate example.

Math extra credit:

The intrepid crew of the USS Jessup has encountered a ravenously hungry space amoeba! If they don’t take quick action, it will swallow them whole, leaving only their iPhone 3472S’s to float aimlessly throughout the galaxy.

Sensors indicate that the amoeba is 120 km in front and 80 km to the right of the USS Jessup. A) At what angle A should the valiant crew fire a replicated ginormous banana cream pie, so that the pie hits the amoeba, thereby allowing the Jessup to escape? B) How far will the pie need to travel in order to hit the amoeba?


(Notice the chibi spaceship — short and squat.)


Physics problem:

Prof. Yee hates mosquitoes! Not only are they disease-spreading, blood-sucking, aerial vampires that don’t sparkle, but they also emit that annoying sound! It comes from their wings, which they beat at an average of 600 times per second. A) What is the frequency of the sound waves from the mosquito wings? B) Assuming the speed of sound is 340 m/s, what is the wavelength of the sound from the mosquito?

My husband is so creative!

    Well played, Professor Chibi! Captain Pythagoras would be delighted, methinks.

    Would you believe that we used to do this type of questions (especially #1) in our 6th grade math, or junior high. It’s too long ago that I do not remember exactly. And too bad, I do not remember how the formula goes.
