The report of the German Physical Society on the Karlsruhe Physics Course is the first attack on the freedom of teaching, which comes directly from physics and not from religious fundamentalists. Why well-trained, supposedly intelligent physicists publicise such nonsense is a mystery to me. What frightens me is the fact that there has been no rebellion within the GPS against this incompetent, malicious and damaging action.

The impossibly stubborn question at the heart of quantum mechanics
/ by Jim Baggott / August 2, 2018 /
Everybody knows by now that quantum mechanics is an extraordinarily
successful scientific theory, on which much of our modern,
tech-obsessed lifestyles depend. It is also completely mad.
Although the theory quite obviously works, we’re left to puzzle over what
we think it’s telling us, with all its ghosts and phantoms; its cats that are
at once both alive and dead; its collapsing wavefunctions; and its seemingly
“spooky” goings-on.
It leaves us with a rather desperate desire to lie down quietly in a darkened room.. . .

Thesis: Small particals in air will lower the dew point.
The water vapour molecule likes to stick with solid particles and condensates faster then assumed according to the conventional dew point prediction.
I just wonder if the correction of dew point is deliberated in the climate models we use today. This could have a large impact because when the overall dew point is lower, the difference in amount of clouds at daytime and night time is bigger. This means that the earth will relatively absorb more heat radiation from the sun then reflecting back in space at night time.
See this expiriment.below.

About ''real'' imaginary numbers in mathematics
and ''not-real'' imaginary numbers in physics.
#
Imaginary numbers are a fine and wonderful refuge
of the divine spirit almost an amphibian between
being and non-being.
/ Gottfried Leibniz /
#
One might think this means that imaginary numbers
are just a mathematical game having nothing to do
with the real world. From the viewpoint of positivist
philosophy, however, one cannot determine what is real.
All one can do is find which mathematical models
describe the universe we live in. It turns out that
a mathematical model involving imaginary time
predicts not only effects we have already observed
but also effects we have not been able to measure yet
nevertheless believe in for other reasons.
So what is real and what is imaginary?
Is the distinction just in our minds?
/ Stephen Hawking /
#
Pi is not merely the ubiquitous factor in high school
geometry problems; it is stitched across the whole
tapestry of mathematics, not just geometry's little
corner of it. Pi occupies a key place in trigonometry too.
It is intimately related to e, and to imaginary numbers.
Pi even shows up in the mathematics of probability
/ Robert Kanigel /
#
The more science I studied, the more I saw that physics
becomes metaphysics and numbers become imaginary
numbers. The farther you go into science, the mushier
the ground gets. You start to say, 'Oh, there is an order
and a spiritual aspect to science.'

Second law of Newton. Experimental evidence: The kinetic energy is equal to the potential energy.
Второй закона Ньютона. Экспериментальное доказательство: Кинетическая энергия равна потенциальной.
Второй закона Ньютона: В инерциальных системах отсчёта, ускорение приобретаемое материальной точкой, прямо пропорционально вызывающей его силе, не зависит от её природы, совпадает с ней по направлению и обратно пропорционально массе материальной точки.
Закон сохранения энергии — фундаментальный закон природы, установленный эмпирически: В изолированную физическую систему, может быть введена скалярная физическая величина, являющаяся функцией параметров системы и называемая энергией, которая сохраняется с течением времени. Закон сохранения энергии является следствием однородности времени, то есть независимости законов физики от момента времени.
Потенциальная энергия тела Ep в поле тяготения Земли, вблизи поверхности, приближённо выражается формулой: Ep=mgh, где m — масса тела, g — ускорение свободного падения, h — высота положения центра масс тела над произвольно выбранным нулевым уровнем. Кинетическая энергия материальной точки mv²/2, является частью полной энергии системы Ep=E=mc² и обусловлена моментом импульса g на высоте h относительно потенциальной энергии Ep n-го порядка.
Согласно закону сохранения энергии, кинетическая энергия материальной точки равна потенциальной энергии импульса g на высоте h относительно потенциальной энергии Ep и имеет вид: mv²/2 = mgh, где m - масса тела, v - скорость (искомая скорость материальной точки), h - высота падения, g - ускорение свободного падения на высоте h. Краткая запись: v = sqrt 2gh (м/с)
Основываясь на законе всемирного тяготения (исключая сопротивление и принимая систему за вакуум), центр масс Земли (скорость вращения ядра) равен: v=sqrt (2 · 98066 (g - ускорение свободного падения) · 6378100 (м - экваториальный радиус Земли) = 11184,58541565131 м/с. В результате получаем обороты относительно g на высоте h, поскольку расстояние в точке не имеет значения.
Экспериментальное доказательство — кинетическая энергия равна потенциальной: Мяч вылетает в обратном направлении из пушки со скоростью 75 км/ч, стоящей на машине, движущейся со скоростью 75 км/ч

Ladies and Gentlemen physics, what do you think about next expression for determine speed of rotation center mass of the Earth?
According to the law conservation of energy, the kinetic energy is equal to the potential energy: mv^2/2 = mgh, where m - is mass of body (she shrinking and not important), v - speed, h - height, g - acceleration of gravity. So speed of free fall v = sqrt (2gh) m/s.
Based on the law of universal gravitation, we can determining center mass of the Earth, and at the same time, we determine rotation speed of core (center mass): sqrt (2 · 9,8066 (g - acceleration of gravity) · 6378100 (m - equatorial radius of Earth) = 11184,58541565131 m/s. Thus we obtain revolutions relative g on the hight h, because distance at the point not have value.

Tradition is a bad advisor when it comes to training young people. Especially in
mechanics, a variety of new, target-group-specific courses could be developed from the abundance of existing theories. A possible approach that has proven itself in engineering education is Systems Physics. Thanks to its interdisciplinary structure with balance equation, constitutive laws and a coherent description of energy, Systems Physics provides a sustainable basis for many academic professions. This paper reveals a small but important part of Systems Physics about the transport of momentum and energy.
