Google’s infa­mous brain-teas­er inter­view ques­tions don’t pre­dict per­for­mance (Busi­ness Insid­er):

Google built a rep­u­ta­tion for ask­ing brain-teas­er ques­tions like “How many hair­cuts do you think hap­pen in Amer­i­ca every year?” They’re sup­posed to test, in the­o­ry, how you tack­le a big prob­lem ana­lyt­i­cal­ly Read the rest of this entry »

Max Your Working Memory with Brain Games and Teasers

Draw the let­ter J on your men­tal sketch­pad. Now draw the let­ter D. Turn it 90 degrees to the left and put it in top of the J. What does this shape resem­ble?

An umbrel­la, of course! You’ve just used your work­ing mem­o­ry. Our work­ing mem­o­ry is a cru­cial part of the mem­o­ry sys­tem, not least because it helps us to fig­ure things out men­tal­ly.

Tem­po­rary work­space
Not only can we store infor­ma­tion in our short-term mem­o­ry, but we can also manip­u­late it. This is why short-term mem­o­ry is some­times also called work­ing mem­o­ry. Work­ing mem­o­ry is our tem­po­rary work­space. We use it in every­day tasks rang­ing from dri­ving (where you need to keep in mind the loca­tion of the cars around you as you nav­i­gate through traf­fic), to prepar­ing a bud­get (where you need to keep in mind one spend­ing cat­e­go­ry while work­ing on anoth­er), to writ­ing a let­ter (where you need to keep in mind all you want to say while devel­op­ing each point a sen­tence at a time).

Math Brain Teaser: How to Choose a Mans Shirt

You have been invit­ed to an impor­tant fundrais­ing gala at your old col­lege and decid­ed that this black-tie event demands a short col­lar super white Ital­ian shirt, like the one you bought years ago for your wed­ding. When you brave­ly tried the wed­ding shirt on (size 16), your wife not­ed that the col­lar suf­fo­cates you and you need about 1/4″ more space every­where in-between your neck and the col­lar all around your neck. What size shirt do you need to buy?  In case you don’t know the shirt size 16 means that a tape wrapped around your neck and two fin­gers posi­tioned flat upfront will mea­sure 16 inch­es.

Math Brain Teaser: Unfinished Thesis

You are spend­ing the sum­mer pol­ish­ing your the­sis in the uni­ver­si­ty library. Every day you take the esca­la­tor into the sub­way, turn right and catch a train going up North to the uni­ver­si­ty. One day you real­ize that the trains on your left going in the oppo­site direc­tion can bring you to the beach. It is sum­mer and noth­ing is wrong with some leisure. You care­ful­ly cal­cu­late that even if you spend half of the remain­ing sum­mer vaca­tion in the library it should be enough to fin­ish the the­sis. You decide to spice up your sum­mer by Read the rest of this entry »
