My husband gives me an A for last night's supper, an incomplete for my ironing, a B plus in bed. My son says I am average, an average mother, but if I put my mind to it I could improve. My daughter believes in Pass/Fail and tells me I pass. Wait 'til they learn I'm dropping out. by Linda Pastan

I've said elsewhere that I reject the idea that counting arises from the fingers.

People often say that base 10 is the obvious choice because we have 10 fingers. Then people come up with other ways of counting fingers to explain away other number systems like the ancient mesopotamian system ("well its because they were counting on individual phalanges!")

As of yesterday I have a new example to undermine the counting-from-fingers idea.

Because if you want a really practical way of counting on your fingers and which will correlate to written numbers, you want base 6.

0..5 on the units hand.

6¹..6⁵ on the sixes hand.

Counts all the way up to 35 and the numbers (digits) you'd write down match 1:1 with your fingers (digits).

If counting arose from the fingers, where's base 6?

EDIT:

I made a silly notation error in the above. Since there are already reblogs I'm not going to change the error, but I feel it needs to be acknowledged.

I wrote 6¹..6⁵ when what I meant was 6×1..6×5.

I'd got distracted by tangential thoughts.

How to Count in Binary on Your Fingers

Okay. There's flooding in Central Texas, which I have family in the middle of, so I'm trying to distract myself. Because on a Discord server I'm on, people were discussing counting on fingers in binary, and I know how, I spent >1.5 hours trying to figure out what was wrong with my photo editor, trying to figure out what was wrong with my backup photo editor, looking for a new photo editor, going back to the first photo editor and figuring out what was wrong. And then about 20 minutes of actually editing photos. So that I could explain to people who almost certainly don't care how to count in binary on your fingers.

Then I thought, hey, maybe Tumblr would like it.

So. Under the cut is how to do this.

This is which fingers of the right hand have what values. Just as base-10 counting has each place being the previous place x 10 (so the rightmost place is 1, the next space to the left is 1 x 10 = 10), in binary each space to the left is previous x 2. So the thumb is the 1s column, the first finger is the 2s column, the second is the 4s column, etc.

Then you just count by places. Each finger that's sticking out is one of that number, each finger folded down is ignored.

The thumb is the only one sticking out, that's 1.

The first finger is the only one sticking out, that's 2.

The first finger and the thumb are sticking out, that's 2+1=3.

Flipping someone the bird is 4.

The next four just continue this pattern:

To convert this system to written binary, everywhere there's a finger sticking out, a 1 goes there, and everywhere there's a folded finger, a 0 goes there. If there are only 0s to the left of the first 1, then those get left off, just as in base-10.

1 = 1 10 = 2 + 0 = 2 11 = 2 + 1 = 3 100 = 4 + 0 + 0 = 4 101 = 4 + 0 + 1 = 5 110 = 4 + 2 + 0 = 6 111 = 4 + 2 + 1 = 7 1000 = 8 + 0 + 0 + 0 = 8

And that's how binary works!

Quick, how many apples are in the photo above? It's easy to see there are three, but thanks to a distinct processing mechanism in your brain, it might have been even easier than you realize. According to a new study, the human brain has two separate ways of processing numbers of things: one system for quantities of four or fewer, and another system for five and up.

Nineteen Birds

Nineteen birds and one bird more, Just make twenty, and that's a score.

To the score then add but one; That will make just twenty-one.

Now add two, and you will see You have made up twenty-three.

If you like these clever tricks. Add three more-for twenty-six.

Then three more, if you have time; Now you’ve got to twenty-nine.

Twenty-nine now quickly take— Add one more and Thirty make. by Anonymous

do you think in hamiltons duel alexander counted in french (in his head) realising the parallels between his sons death and the one he was about to face? Its stated in guns and ships that he speaks french, and phillip counted in the same language on his deathbed.

Am i late to the party on this or am i insane???
