Dating Among Friends

The best way, in my opinion, for finding a mate, is to look into your circle of friends. I don’t mean “actively” looking, but I think it’s easier than the other ways to find love.

You spend time with your friends, and your friends’ friends. Like “dating at work”, you get to know the person before moving on to something more intimate, and I think that’s the most important thing. People need to take more time before falling into a relationship.

If things don’t turn out good between you, this could become more complicated, or embarrassing. Just because someone is not your friend anymore doesn’t mean he or she will leave your friend circle. That person could still be nearby. Of course, it all depends on how you broke up, and the circumstances leading to it.

Clothing Size

2011/10/25 4 comments

Why is it so complicated to find a piece of clothing that fits?

My waist is 82-83 centimeters, so around 32.5 inches. You would think that buying a pair of 32″ or 34″ pants would fit, but it’s not that easy. My dress pants are from Mexx and are size 34s. If I measure, they are really 34 inches at the waist. On the other hand, my jeans are from Gap and are size 32s. If I measure again, I can find out they are 35 inches at the waist! No wonder they are too big for me! (Actually, all my pants are a bit too big, because I lost some weight in the last two years.)

So why are companies doing that?

First, let’s look at the women’s side. In the US and Canada, the size of a piece of clothing is unitless. That means that, for example, a size 5 blouse is usually around a certain measure. The problem is that, because of vanity sizing, people are more prone to buy that piece of clothing if they are in a good mood, but the companies are merely changing the sizes over time.

This has led to size 0, size 00, and subzero sizes. Totally ridiculous. This unitless system is too easy to modify over the years. And if you travel to another country, the sizes are not the same.

The best (and most logical) way for this system to function would be that everything be written in centimeters. That would be a worldwide standard. Fines could also be given to companies (like Gap) that advertise the wrong measure. In an ideal world:

Area Problem

That’s a small mathematical problem that was bugging my mind a few years ago. Back then, I had solved it by logic, but I thought I could put some numbers in order to know exactly what’s going on.

The problem is that we have four shapes, and by only moving them, we get a different area.

The area of the red and yellow triangles is (21 × 8) / 2 = 84 each, and the area of the green and blue triangles is (13 × 8) + ( (13 – 8) × 13) / 2 = 136.5 each. That gives 84 × 2 + 136.5 × 2 = 441, so what’s wrong with the second picture?
Please take a few moments to think about it. Sleep on it if you want! There’s always that sense of pride when you success in doing something by yourself.
The answer is in the angles. They seem to be the same, but are not. The red and yellow triangle’s slope is (21 / 8) = 2.625, while the green and blue triangle’s slope is (13 / (13 – 8)) = 2.6. Another way to make sure is to calculate the angles like this:
That means that, on the second picture, the long edge made by the green and red triangles is not a straight line. If I exaggerate the difference in the angles (for comprehension purposes), it would give something like this, which explains the difference in areas:
A few years ago, it wasn’t really this problem that I saw, but something that can be solved in exactly the same way. It looked like that:
The rest of the post is only some mathematical rambling…
If we really want to be crazy, we can verify that the empty shape inside has an area of 1 (which is the initial difference between the two areas). We should divide the problem into two large triangles, calculate the area of one triangle, then multiply by 2 to find the empty area inside. I’ll keep the calculations as precise as possible.
First, we can calculate all the hypotenuses and angles:
Which results in the following triangle:
We can use trigonometry if we divide the triangle into two right triangles, and calculate the angles:
Then it’s only a matter of calculating the other sides with sine and cosine:
and calculating both triangles’ areas. It looks messy, but I wanted to show all the steps.
Square root of x, squared, equals x, and sin(θ) × cos(θ) = sin(2θ)/2, so that simplifies to:
We had two large triangles, so this gives us 1, which is the difference in area that was the subject of this post from the beginning.
Writing this post taught me that I should do all the equations on paper first, in case I make a mistake somewhere. Fortunately, I did not, but I was scared to have to correct all the images if I did.

How Come the Human Race is not Extinct?

I was thinking about how fragile young children are. Everything they do is irrational, and it’s our job to teach them so they can learn and experience the world around them.

But man, they are so fragile I sometimes wonder how come our race is not extinct. Children are the best magnets to diseases and viruses, and it doesn’t help that they put everything they find in their mouths, be it a clean sock, or some unknown thing in a pile of suspicious dust in a corner. I guess only a minority of illnesses can be fatal.

What children put in their mouths can also be round, coincidentally exactly the same size as their throats. They can suffocate and scare their parents to death. Evolution has not a role to play in this, because in the past, the only things they could suffocate on would be some berries and small rocks. With human evolution stopped, children will never know innately about this danger.

Acting irrationally, and doing things without the ability to think before, can easily lead to injuries to themselves and others. Drinking anything that look like juice is particularly bad, when you look at what’s under the sink. Parents are not omnipresent, and accidents do happen (unfortunately). Children play in the stairs, cross the street without looking, and do all sort of things that they stop doing at a greater age, after they learn by experience.

I guess we can all be grateful that only a fraction of what children do lead to a tragedy, or else we wouldn’t be there, would we?

Funeral Clown

I was talking with a friend the other day about some practical jokes that would be considered sociopathic. One of them was particularly of interest, and that was calling a clown to a funeral.

Granted, that would be a sick joke, as much to the poor clown as to the mourning people. But it definitely would be epic.

If I ever know the date and time for my own funeral, I would call a clown. Heck, I would even ask that as my dying wish! People in a funeral are usually mourning and sad and crying – but I would not want them to! This would be the last time they see me – might as well make it a happy occasion! I’d like people to laugh and remember all the good times we had together. I’d want people to cry from laughter, not sadness. That would be my funeral, and there would be clowns, one or two comedians, and good music from live musicians. Helium balloons, and what the heck, sulfur hexafluoride balloons, for even more laughs! Then just before all this is over and the sun has set, fireworks! Giant flowers of light, so that I can go with a bang.

Oh, and while we’re at it, burgers, hot dogs, and steaks on the BBQ outside.
