See the full Portal Walkthrough here: goo.gl âžœ Portal Walkthrough â–¼ Portal: Chapter 7 Portal vs. Lewis as he takes on this mind bending game where he will have to work through brain aching test chambers only to see that the puzzles get harder and harder. As a general note, Lewis has no idea what he is doing as he has never played the game before. Expect him to get stuck! Enjoy. â–ºPortalâ–¼ Portal takes place in the Enrichment Center for Aperture Laboratoriesâ€"also known as Aperture Scienceâ€"which is the fictional research corporation responsible for the creation of the portal gun. According to information presented in Portal 2, the location of the complex is in the Upper Peninsula of Michigan. Information about the company, developed by Valve for creating the setting of the game, is revealed during the game and via the real-world promotional website. According to the Aperture Science Web site, Cave Johnson founded the company in 1953 for the sole purpo se of making shower curtains for the US military. However, after becoming mentally unstable from lunar poisoning in 1978, Johnson created a three-tier research and development plan to make his organization successful. The first two tiers, the Counter-Heimlich Maneuver (a maneuver designed to ensure choking) and the Take-A-Wish Foundation (a program to give the wishes of dying children to unrelated, entirely healthy adults), were commercial failures and led to an investigation of the company by the US Senate. However, when the ...
Portal - Walkthrough Part 4 [Chapter 7: Test Chamber 15-16] - W/Commentary
In a previous article "Let's do a green science fair project" we had a look at the effects on soil erosion and rainfall of the cutting down of the rain forests. Our theme is still having a look at how nature works and what we can do to preserve our planet. Today we are going to have a look at trees and how they grow. We are going to try and understand why they differ in different parts of the world. This is a very good science fair project for someone who is interested in nature and loves going for walks. Remember, when you are doing this science fair project to take an adult with you to ensure your safety. Please do not go wandering on your own. To be honest this is probably a good science fair project for adults as well! A walk in nature is always relaxing.
In different parts of the world trees grow differently according to the kind of weather you get in different parts of the world. This is a good science fair project to not only learn about trees but also wha t the effect of weather is on the way that trees grow. Trees can be studied in your garden or when you go for a walk in a park. Choose an area that has a lot of different trees that you can study.
First we need to know a little more about trees in general before we continue. You get several different kinds of trees. In the tropical rainforest, at the equator, the weather never changes much and winter and summer have temperatures that are very close together. We have already seen how the trees influence the rainfall in our previous article. In the tropical forests most trees are evergreen as heat and water are not a problem. In areas where the weather is moderate trees have broad leaves that they shed during winter to slow down the tree's metabolism and conserve water for when it is less plentiful because the ground water is frozen and this also reduces damage by frost.
Our first project is to try and identify some trees in our area and then in a later project we are going to measure them.
This is what you will need to help you identify them:
* A field guide to the local trees
* A notebook
* A pen
* Colored pencils
This is what you need to do when identifying the trees:
1. Whilst walking in the area you have chosen, try and identify the trees according to your field guide.
2. Look at things such the general height and shape of the trees.
3. Use the appearance of the bark as well as the leaves to compare with your field guide. Look at the color and shape of the leaves and the fruits and the seeds of the trees to help you.
4. Make meticulous notes and drawings for your display.
5. Give attention to the height of the trees to help you.
6. If it is possible take samples of the leaves, fruit and seeds. (Do not pick them from the trees, as that is mostly forbidden as people damages the trees, only collect leaves, fruit and seeds that h as fallen of naturally.)
7. To use them as a part of your display, press them between the pages of a book. (Place them between tissue paper to prevent their juices damaging your book.)
8. When you get home, do your display and note what characteristics you have used to decide on each tree.
9. Give meticulous details of all the reasons such as color and shape of leaves, fruit or seeds.
10. Try to read up on the trees and use it as motivation for your decisions.
Now you know more about trees, their leaves and seeds, can you understand why cutting out the rain forests are such a bad idea?
This is a very good science fair project for budding biologists.

What role does influencing human behavior play in economics? In the midst of the recession(which began in 2007 but no one acknowledged till months later) we, the educated ones, were whispered that we mustn't say 'recession' because telling the truth about the recession would only exacerbate it. I see however many times on Fox News and others attempts at shaping the mind and social behavior in such a way as to influence economic and financial behavior of its viewers and society at large. If economics can be boiled down to influencing human behavior, not simply predicting it, how valid a science is economics? Best answer for If economics is a social science and analysis boils down to predicting human behavior?:
Answer by Andrea
Economics the science is valid. Media manipulation of people is what you are questioning. One can not allow one single viewpoint that is delivered with a slant- of any sort- so ingrained and then consider that real economic advice. However I must say that propaganda and media manipulation based on behavioral analysis is also a quite valid field. Based on the success of such things one can hardly discount the viability of such techniques.
Answer by coldfuse
As my wise old Money & Banking professor said, "The questions in Economics never change. The answers do." That economics is not an exact science does not invalidate it. I work with data on labor and demographics on a daily basis, and believe the information is the best available even if it is not precise. In college, many people refuse to take economics, thinking it is on the level of rocket science. All of a sudden, in debates with other people, and even with economists, folks think they are economics experts! How would you respond, for example, to Harvard economist Martin Feldstein?
