In the final years of the First World War, the Russian Empire was coming to its end. It had been devastated by revolution and finally transformed into the first Communist country in the World. In the years following the Revolution, non-Russian nations that lived under the House of Romanov sought to secure their long-lost independence. One of these was Ukrainе. From 1917 until 1921, the Ukrainians had struggled to build and secure an independent country, fighting against the new regime, against their neighbors in the west, and also among themselves.

Linear Algebra on Khan Academy: Have you ever wondered what the difference is between speed and velocity? Ever try to visualize in four dimensions or six or seven? Linear algebra describes things in two dimensions, but many of the concepts can be extended into three, four or more. Linear algebra implies two dimensional reasoning, however, the concepts covered in linear algebra provide the basis for multi-dimensional representations of mathematical reasoning. Matrices, vectors, vector spaces, transformations, eigenvectors/values all help us to visualize and understand multi dimensional concepts. This is an advanced course normally taken by science or engineering majors after taking at least two semesters of calculus (although calculus really isn't a prereq) so don't confuse this with regular high school algebra.

About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.

This 3D animation explains the hormonal changes during the menstrual cycle. The menstrual cycle begins with menstrual bleeding, marking the follicular phase’s first day. When the follicular phase begins, levels of estrogen and progesterone are low. As a result, the top layers of the uterus’s thickened lining break down and are shed, and menstrual bleeding occurs.

About this time, the pituitary gland starts sending follicle-stimulating hormone to your ovaries, stimulating the development of 5 to 20 follicles in the ovaries. Each follicle contains an immature egg and produces estrogen. One follicle will soon begin to grow faster than others. This is called the dominant follicle. As the follicle grows, the levels of estrogen in the blood rise significantly. This increase in estrogen begins to inhibit the secretion of the follicle-stimulating hormone. The fall in follicle-stimulating hormone allows smaller follicles to die off. They are, in effect, "starved" of follicle-stimulating hormone.

The increasing amount of estrogen in your body also ensures that the lining of your womb thickens with nutrients and blood. This is so that if you do get pregnant, the fertilized egg will have everything it needs to grow.

The ovulatory phase begins with a rise in the levels of luteinizing hormone and follicle-stimulating hormone. The surge in the luteinizing hormone triggers one of the most prominent follicles to pop open and release its egg, which heads into the fallopian tube and starts its journey toward the uterus. Ovulation usually occurs 16 to 32 hours after the beginning of the surge, around day 14 of the menstrual cycle.

During the luteal phase, the levels of the luteinizing hormone and follicle-stimulating hormone decrease. The ruptured follicle closes after releasing the egg and forms a corpus luteum, which produces estrogen and progesterone, which cause the lining of the uterus to thicken even more. If an egg is fertilized, progesterone supports early pregnancy. But if no fertilization occurs, the corpus luteum will break down between 9 and 11 days after ovulation. This results in a drop in estrogen and progesterone levels, bringing us back to the first stage of menstruation if no pregnancy has occurred.
