TURBINE, GENERATOR, ENGINE Comment these facts If a person yelled for 8 years, 7 months, and 6 days, he or she would produce enough energy to heat one cup of coffee. Energy cannot be destroyed or created—only transformed. The top seven oil consumers combined use more than half of the world’s total. The United States alone uses more than a quarter. Nuclear power produces around 13% of the world's electricity. Space missions have been using solar energy to power spaceships since 1958. Although the sun is over 90 million miles from the Earth, it takes less than 10 minutes for light to speed across that distance. Petroleum oil provided 18 percent of energy for electricity in 1973 and less than 1 percent in 2011.

What kinds of fuel can means of transport use? What is the energy of the future? What do you think? How is energy transported? What is the difference between a wire and a pipeline? There are the principles of energetics. Can you explain them and comment them? Zeroth principle of energetics If two thermodynamic systems A and B are in thermal equilibrium, and B and C are also in thermal equilibrium, then A and C are in thermal equilibrium. First principle of energetics The increase in the internal energy of a system is equal to the amount of energy added to the system by heating, minus the amount lost in the form of work done by the system on its surroundings. Second principle of energetics The total entropy of any isolated thermodynamic system tends to increase over time, approaching a maximum value. Third principle of energetics As a system approaches absolute zero of temperature all processes cease and the entropy of the system approaches a minimum value or zero for the case of a perfect crystalline substance. Fourth principle of energetics In the field of ecological energetics H.T. Odum considered maximum power, the fourth principle of energetics. Odum also proposed the maximum empower principle as a corollary of the maximum power principle, and considered it to describe the propensities of evolutionary self-organization. Fifth principle of energetics The energy quality factor increases hierarchically. Flows of energy develop hierarchical webs in which inflowing energies interact and are transformed by work processes into energy forms of higher quality that feedback amplifier actions, helping to maximise the power of the system. Sixth principle of energetics Material cycles have hierarchical patterns measured by the energy/mass ratio that determines its zone and pulse frequency in the energy hierarchy.

31 Can you comment these 3 Newton´s laws of motion? What do they mean?
An object in motion tends to remain in motion and an object at rest tends to remain at rest. Force equals mass times acceleration. For every action there is an equal and opposite reaction. What do you know about the motion of these objects?

32 1T 2T 3F 4T 5F 6T 7F 8T 9F 10F First law of motion
Choose whether the following statements are true or false Everything in the universe moves. The Sun is moving around our galaxy. There are four Newton´s laws of motion. Changes in motion won't just happen on their own. Acceleration is a measure of how much the velocity of an object changes in 5 minutes. Mass is the amount of something and is measured in grams (or kilograms). Potential energy is observed when an object is in motion. If you do not apply a force to an object in motion, it will forever stay in motion. Friction can be eliminated with modern materials. Gravity is increased when you increase distance. 1T 2T 3F 4T 5F 6T 7F 8T 9F 10F Devide the following movements according to Newton´s laws of motion Can you describe each movement?

55 Famous maths quotes... what do you think about them?
If people do not believe that mathematics is simple, it is only because they do not realize how complicated life is.  ~John Louis von Neumann Pure mathematics is, in its way, the poetry of logical ideas.  ~Albert Einstein The essence of mathematics is not to make simple things complicated, but to make complicated things simple.  ~S. Gudder Go down deep enough into anything and you will find mathematics.  ~Dean Schlicter Sometimes it is useful to know how large your zero is.  ~Author Unknown If there is a God, he's a great mathematician.  ~Paul Dirac Infinity is a floorless room without walls or ceiling.  ~Author Unknown One cannot escape the feeling that these mathematical formulas have an independent existence and an intelligence of their own, that they are wiser than we are, wiser even than their discoverers...  ~Heinrich Hertz You and maths When did you become interested in maths? Why did you decide to study it? What about your studies? Where did you study and how difficult was it? Why did you become a teacher? Say something about your school. Say something about maths in each grade – what do you teach there? Which fields of maths are the most popular and which ones are the least popular of all? Why do the children like / dislike maths? What kind of tool do you use during your lessons? How often do you test your students? What methods do you use to explain various fields of maths? What do you think about the „state maturitas“? Do you think everyone should take the state maturita from maths? Why is maths important for our future? How do you think young students should be attracted to mathematical universities? What jobs can the students do when they finish mathemtical universities? Which mathematical problems do you think scientists will be solving in the future? Do you think you will spend your life as a teacher of mathematics?
