Most often, the question “why is the snow white” is asked by children, yet not all adults know the answer as well. Why it’s white and not red, green or whatever? Moreover, there’s one more question concerning snow. Why is the ice transparent while the snow is white? The answer to both of these questions is connected with two things: the very notion of color and the structure of snow and ice. We’ll start with the first problem. Let’s explain it from physics perspective. (more…)
It’s time to summarize the results of our work through the last year. The key value of all our activities is the percent of homework assignments successfully done and we totally understand the crucial importance and responsibility in handling tasks of our customers. What can be worse than badly produced, damaged or incompletely equipped product you buy? A joy of purchase spares place to frustration and desire to receive a refund immediately.
This is fully applicable to homework service and gets even worse as often you are not allowed to resubmit the assignment or pass the test one more time. That’s why we constantly monitor our performance to minimize the risks of failing the task and thus upsetting and losing trust of our customers. We implicate various techniques of improving the quality of the work done, delivery and customer support service. (more…)
You’ve probably ever observed snowflakes. Even with the naked eye you can notice that none of them ever repeats another. In one cubic meter of snow there are approximately 350 million snowflakes, and each of them is unique. How’s that possible? To answer that question let’s consider the physics of snowflake formation. It’s interesting, that you can not have a pentagonal or heptagonal snowflake, they all have strictly hexagonal shape. (more…)
Wait do you hear that? Is that Ho ho ho from Santa? (or from the teacher setting your finals?) Anyway, you’re probably decorating your dorm right now or taking a shopping walk in anticipation of Christmas. There are a lot of things for students to do on holidays, and little time to get prepared because of finals. Probably you won’t argue that Christmas tree is a must-have. If you still don’t have one, pick one of our geeky tree ideas. Another thing is gifts. And that’s something to think about! Check our list of best Christmas gifts for geeks and pick some ideas for your friends and family.
Previously we’ve discussed the chain rule for derivatives and how to apply it. However, sometimes using chain rule alone is not enough and you’re also required to apply other rules for derivatives to get the correct answer. Today we’ll consider one of such cases. (more…)
Christmas is around the corner and everyone is thinking about presents and decorations (unless you still have finals to pass..). Traditional glass ornaments and laces are adorable; however, if you’re bored with this stuff (or simply don’t have any at the dorm), you can create decorations for college in modern way, using almost everything, the only limitation is your imagination. Some science lovers cannot go without science even on holidays and thus yield sometimes strange, or even crazy ideas and hand-made implementations. We don’t recommend you to construct the foregoing stuff at home, as without understanding of physics and proper safety arrangements this could turn into troubles. If you are not a physics lover, proceed to other ideas for Christmas trees in this article. So look! (more…)
Do you know who are bulls and bears? Of course, this is not about zoology 🙂 Speaking of economics and financial markets, bulls and bears – these personages have become classics – represent the two major market forces, buyers and sellers. Initially, such a comparison was used on the stock exchanges, but later it made its way in respect of any other participants in financial markets.
