The year is 1917. Millions of Russians had been either killed or wounded.

The Russian people were angry at Tsar Nicholas II for getting Russia into the war.

Helmets and Body Armor in Modern Warfare
By Bashford Dean

Students learn about the role engineers and mathematicians play in developing the perfect bungee cord length by simulating and experimenting with bungee jumping using washers and rubber bands. Working as if they are engineers for a (hypothetical) amusement park, students are challenged to develop a show-stopping bungee jumping ride that is safe. To do this, they must find the maximum length of the bungee cord that permits jumpers (such as brave Washy!) to get as close to the ground as possible without going "splat"! This requires them to learn about force and displacement and run an experiment. Student teams collect and plot displacement data and calculate the slope, linear equation of the line of best fit and spring constant using Hooke's law. Students make hypotheses, interpret scatter plots looking for correlations, and consider possible sources of error. An activity worksheet, pre/post quizzes and a PowerPoint® presentation are included.

Every year, hundreds of millions of people voluntarily turn their lives upside down by setting their clocks forward one hour in the spring and back one hour in the autumn on a particular date mandated by the government wherever they happen to live. Daylight saving time is a perfect example of how a few people with the best of intentions can end up annoying millions of the rest of us for the better part of a century. And it’s time we take an honest look at how we got to this place where half the world comes unstuck in time twice a year, and ask if the supposed advantages for springing forward and falling back still hold up! #daylightsavingtime #DST

Trigonometry on Khan Academy: Big, fancy word, right? Don't be fooled. Looking at the prefix, tri-, you could probably assume that trigonometry ("trig" as it's sometimes called) has something to do with triangles. You would be right! Trig is the study of the properties of triangles. Why is it important? It's used in measuring precise distances, particularly in industries like satellite systems and sciences like astronomy. It's not only space, however. Trig is present in architecture and music, too. Now you may wonder...how is knowing the measurement and properties of triangles relevant to music?? THAT is a great question. Maybe you'll learn the answer from us in these tutorials!

Precalculus on Khan Academy: You may think that precalculus is simply the course you take before calculus. You would be right, of course, but that definition doesn't mean anything unless you have some knowledge of what calculus is. Let's keep it simple, shall we? Calculus is a conceptual framework which provides systematic techniques for solving problems. These problems are appropriately applicable to analytic geometry and algebra. Therefore....precalculus gives you the background for the mathematical concepts, problems, issues and techniques that appear in calculus, including trigonometry, functions, complex numbers, vectors, matrices, and others. There you have it ladies and gentlemen....an introduction to precalculus!

Hi! Welcome to Improved Math!

If you want to learn how to add negative integers, this video is for you. When adding all positive integers, your answer will always be positive. When adding all negative integers, the answer will always be negative. When adding both positive and negative integers together, you will subtract the absolute values of the integers and the answer will be in the sign of the integer with the highest absolute value. Don’t forget to check out the bonus problem and leave me your answer in the comments!

Understanding basic math isn’t just about crunching numbers; it's about fine tuning problem-solving abilities, making informed decisions, and gaining deeper insight into the world around us. From everyday tasks to complex situations, math plays a pivotal role.

Just as important is cultivating critical thinking skills. Learning how to analyze and evaluate information is needed to arrive at well-informed conclusions. Discover why these skills are the cornerstone of innovation, creativity and rational decision-making.

Math isn’t just confined to the classroom but is essential in all aspects of life from personal finance and career success to daily decision-making and creative endeavors.

This algebra math video tutorial focuses on simplifying exponents with fractions, variables, and negative exponents including examples involving multiplication and division of monomials. This video discusses the basic properties of exponents and their rules such as the product rule, power rule, and quotient rule. It explains how to simplify exponential expressions with zero exponents and tells you when you add, subtract, or multiply two exponents together. This video contains plenty of examples and practice problems.

Title: What is the bottom number of a fraction - Fast And Easy Math Learning Videos

In this lesson, you will begin to learn about fractions. Fractions are used to describe the PARTS of whole units. A fraction is written like this:
In this lesson, you'll learn about the BOTTOM number of a fraction.
To create a fraction we divide a whole unit into equal parts. The BOTTOM number of a fraction tells us the number of equal parts in each whole unit. Here's an example. This box is one whole unit. We'll divide the box into four equal parts...
Since the parts are equal each part is a fraction of the whole unit. There are four equal parts in all, so the BOTTOM number of each fraction is four.
In this example there are three whole units.
One.
Two.
Three.
Each whole unit is exactly the same size. When whole units are the same size we can divide them into fractions. Each of these whole units is still divided into four equal parts.
Here’s another way of looking at the equal parts of whole units or fractions. There are six whole units and each whole unit is divided into two equal parts. We can put the whole units together like this.
Each whole unit is now a line instead of a box. The tallest line show the beginning and end of each whole unit.
We’ve just created a number line. A number line is another way to show fractions which are just equal parts of whole units.
Notice this arrow.
The arrow points to one of the fractions on the number line.
You’ll learn to write the name for fractions like this. For this lesson you will ONLY write the BOTTOM number of the fraction.
In this example there are two equal parts in each whole unit.
So the bottom number for this fraction, is two
Here’s a different fraction on the same number line.
Each whole unit is still divided into two equal parts so the bottom number for this fraction is also two.
Here’s another example. There are FOUR parts in each whole unit, so the bottom number for this fraction is four.
The bottom number for this fraction is also 4.
And the bottom number for this fraction is also 4. For any fraction on this number line the bottom number will always be four since each whole unit has four equal parts.
In the remainder of this lesson you will write the bottom number for the fraction shown by the arrow on a number line like these.

There is an absolutely weird, but surprisingly common phenomenon called sensory adaptation that you experience every day in countless ways without even realizing it. Without this very strange phenomenon, you would be lost, overwhelmed, and completely unable to navigate the external world. In this episode, we’ll explore the many ways your brain “tunes out” most of what’s going on around you so that you can be the high-functioning smart people that we know you are.
