Have you ever been to the Grand Canyon? Perhaps you have seen it in photographs or videos. Imagine climbing a trail from the top of the canyon down to its base. As you walk, you pass distinct rock layers, each with its own unique colors and textures. In a way, you are traveling back through time as you descend into the canyon! The earth is a dynamic system and it is constantly changing, even when we can’t see those changes on a daily basis. Over the course of hundreds, thousands, and millions of years, the landscape of the earth changes dramatically. New rock layers form. Faults break apart the crust.

I have said, in the past, that you should move toward full frame sensors. I have always championed full frame sensors. At the end of the day, full frame sensors beat APS sized and smaller sensors. The whole reason I bought an original x was because it had the largest sensor I could find in a small camera.

Algebra problems like this one are at the heart of a dispute over the level of math deemed necessary to earn an associate degree or transfer to a four-year college. How necessary is intermediate algebra, a high school-level course on factoring trinomials, graphing exponential functions and memorizing formulas that most non-math or science students will rarely use in everyday life or for the rest of college?
A growing number of educators have challenged this long-held gold standard of math in California, particularly at a time when two-year colleges are under increasing pressure to improve completion rates. More than 3 out of 4 community college students in California cannot pass the placement exam and are forced to take one, two or more semesters of remedial math.
Discouraged or frustrated, most drop out before ever earning a degree. Does the system need to change? Here is a look at what some in the field have to say about this highly charged debate. What is the current requirement? But many innovations have proved controversial. Others argue that intermediate algebra is a necessary path for higher-paying science, engineering and math careers. And you have new, younger faculty that equally passionately believe in all the new experiments on ‘how can we make students more successful?
For decades, the standard high school and college math curriculum in America has been based on two years of algebra and a year of geometry — a track that prepares students to eventually take calculus. Intermediate algebra builds on these concepts but is more technical and specific — some critics have compared this to studying Latin, which has lost its relevance as a college requirement for all.

Academic Institution Partnership Hydrogeological Survey of Somalia Despite groundwater being the main source of water for humans, agriculture and livestock, there is neither a hydrogeological map nor a sound policy for groundwater management and exploration in Somalia. SWALIM undertook a quantitative and updated assessment of the groundwater resources of Somaliland and Puntland and the set-up of a system for groundwater level monitoring.

It’s up to us to develop the sensitivity to pick up on it. Pedantry can be the enemy of insight. This gives students the idea that there is a book somewhere with all the right answers to all of the interesting questions, and that teachers know those answers. And if one could get hold of the book, one would have everything settled. That’s so unlike the true nature of mathematics.
Experience comes from bad judgement. The details are available from the author on request. The author does hope someone will check the calculations, because he does not have a great deal of faith in his ability to carry through the details in a fault-free manner. He hopes however that the answers are qualitatively correct as stated.
Every time we count pairs, we learn something from it. I’d used email since about , and it seems to me that 15 years of email is plenty for one lifetime. It is the willingness of his teacher to listen to him.

Math Sums Practice Math Problems Luckily for parents and teachers, there are plenty of websites that provide math problems for extra math practice. For example, for primary and middle school students there are 1st grade math problems, 2nd grade math problems, 3rd grade math problems, 4th grade math problems, 5th grade math problems, 6th grade math problems and 7th grade math problems. There are also math problems classified as addition problems , subtraction problems , multiplication problems and division problems.
Importance of Practice Math Problems Children will benefit greatly from using math problems to practice their math skills. This is why many parents like to give their children additional math practice at home with freely available math problems from the internet. Math Word Problems Math word problems require greater skill than simple math problems.
This is because math word problems require reading and comprehension skills in addition to basic math skills. Further, in order to solve math word problems, children must be able to understand the relationship between math equations and simple everyday situations. Therefore, math word problems are a good way to highlight the importance of math in everyday life. Practicing math word problems helps kids master the skills they need to answer such questions.

I’ve done a pretty good job of beating the smart people problems. Society puts smart people on quite a lofty pedestal but there’s some real downsides to being highly intelligent.

Never fear — Plus is here! In this article we’ll look at one of the central questions of dating: It’s a tricky question, and as with many tricky questions, mathematics has an answer of sorts: Is this the one? Why is that a good strategy? You don’t want to go for the very first person who comes along, even if they are great, because someone better might turn up later. On the other hand, you don’t want to be too choosy: It’s a question of maximising probabilities.
The value of depends on your habits — perhaps you meet lots of people through dating apps, or perhaps you only meet them through close friends and work. That in itself is a tricky task, but perhaps you can come up with some system, or just use your gut feeling. Your strategy is to date of the people and then settle with the next person who is better. It shows the values of on the horizontal axis and the best value of , the one that maximises the probability of ending up with X, on the vertical axis.
You can see that, as gets larger, the optimal value of settles down nicely to around.

Perfect Numbers The Pythagoreans produced a theory of numbers comprised of numerology and scientific speculation. In their numerology, even numbers were feminine and odd numbers masculine. The numbers also represented abstract concepts such as 1 stood for reason, 2 stood for opinion, 3 stood for harmony, 4 stood for justice, and so on. Their arithmetica had a theory of special classes of numbers. A perfect number is a positive integer that is equal to the sum of it divisors.
However, for the case of a perfect number, the number itself is not included in the sum.

It’s important to use problems that will take all your kids about the same amount of time to complete. To differentiate, use a mix of difficulties. If you will have the whole class working together, you need as many problems as students. If you are breaking the class into two distinct groups, you need half as many problems as students, but two copies.
