Among the disputes facing many homeowners are basement waterproof issues. If waterproofing is not done properly, it can cause a domino consequence. Hence, learning valuable basement waterproofing information will avoid this crisis.

How is information preserved during cell division ? Animated sequences plunge us into and guide us through this mystery. Grab on to one of the passing genetic flows and come surf!

This is a great animation of the flow of genetic material. It is very useful for many grades and many levels of understanding. You can just get the bare bones or you can delve into great depths about DNA and the movement of genetic material through the cell.

There are many different options available when it comes to setting up an E-commerce website, but no matter how you go about it, you will need a full array of options when establishing your website in the beginning.

There are now lots of options available to you if you want to make an E-commerce software. Now the reality of it all is that e-commerce is the future of retail and in fact nearly all business, with the growth of internet usage all over the world and the increased use of computers it is vital that if a business really wants to achieve real success then it will invest in ecommerce and in particular Ecommerce Software.

Recently I've been trying to teach my two and a half year old child to learn some letters from the alphabet. I want him to learn to write his name, and at least recognize all the letters of the alphabet. I figure this is not too early for him as he is really into drawing and "reading" books and even pretending he is reading the letters. So everyday I sit with him at the table, like a big boy, and we do "school work" for about 1/2 an hour. It's fun for him, because he thinks he's like my older two sons, doing his homework.

I had many requests for a step by step instruction of making the "Hydraulic Crane".

Although this wasn't my construction (one of my brilliant students did this one for a project that I assigned), I can figure out the basics from what I saw.

We were playing Settlers of Catan the other day. If you don't know it, you should immediately go out and buy it, because it is a fantastic game... one of the best strategy / board games ever. But back to my topic... The game relies on die randomness. From basic math / probability, we know that when rolling two dice, the sum of 7 has the highest probability of getting rolled. Next, the sums of 6 and 8 would have the next best chance. More importantly, the 6 and the 8 would have equal chance of getting rolled. Then 5 and 9 and so on. This is easily shown with a table (sample space) displaying all the possible outcomes of rolling two dice and then counting the number of possible outcomes of getting a sum of 7, sum of 6, sum of 8 etc.

But when we were playing our board game, it seemed that these random rules didn't apply all that well. The higher numbers seemed to come up way more than the lower ones. For instance 9 came up way more than 5. First we thought that our dies are not well balanced, so we traded them from a set from Monopoly, but the same trend continued. Unhappy with this (I lost the game because I chose lower numbers in Settlers and they hardly came up) I decided to look into this more.

The Genetic Algorithm Game - Solving a Complex Pathway Problem with Evolution:

You start with a complex map (attached here as a pdf file, or see the picture above or create your own map). There is a way of getting from point A to area B in very many different combinations. Figuring out the fastest way to get there is the object of the game.

There are five sections (decisions) to the path. Starting at point A, once could go left (L), straight (S), or right (R). Each time you reach the next point (crossroads) you can choose to go left, straigt, or right. Since the path has five such points, the "genetic code" will consist of five such decisions.

For example, one student in the class can go first left, then right, then left, then straight, and finally straight to reach the final destination of B. For this student, the genetic code would be: LRLSS.
