Betz's law indicates the maximum power that can be extracted from the wind, independent of the design of a wind turbine in open flow. It was published in 1919, by the German physicist Albert Betz.[1] The law is derived from the principles of conservation of mass and momentum of the air stream flowing through an idealized "actuator disk" that extracts energy from the wind stream. According to Betz's law, no turbine can capture more than 16/27 (59.3%) of the kinetic energy in wind. The factor 16/27 (0.593) is known as Betz's coefficient. Practical utility-scale wind turbines achieve at peak 75% to 80% of the Betz limit.[2][3]
The Betz limit is based on an open disk actuator. If a diffuser is used to collect additional wind flow and direct it through the turbine, more energy can be extracted, but the limit still applies to the cross-section of the entire structure.A wind turbine is a device that converts kinetic energy from the wind into electrical power. The term appears to have migrated from parallel hydroelectric technology (rotary propeller). The technical description for this type of machine is an aerofoil-powered generator.
The result of over a millennium of windmill development and modern engineering, today's wind turbines are manufactured in a wide range of vertical and horizontal axis types. The smallest turbines are used for applications such as battery charging for auxiliary power for boats or caravans or to power traffic warning signs. Slightly larger turbines can be used for making contributions to a domestic power supply while selling unused power back to the utility supplier via the electrical grid. Arrays of large turbines, known as wind farms, are becoming an increasingly important source of renewable energy and are used by many countries as part of a strategy to reduce their reliance on fossil fuels.
Sea waves have high energy densities, the highest among renewable energy sources with the natural seasonal variability of wave energy following the electricity demand in temperate climates securing energy supplies in remote regions.

What are the benefits of the numerical miracle?
1- A method for guiding atheists in this era.
2- To increase the certainty that the Qur’an is God’s book.
3. An effective method to calling for God.
4. To discover more wonders of the Qur’an..
The miracle could be a method to reach the guidance. All prophets used the miracle to guide people to the straight way and to prove that they are sincere in their calling for God...
The miracle: is the best method to guide people to the way of Allah be He blessed and exalted.
It is an extraordinary support from Allah to His prophets which is over the abilities of ordinary people to prove that the divine message is sincere.
For example: the miracle of Prophet Moses was the stick, the miracle of Prophet Saleh was the camel and the miracle of Jesus was the Revival of the dead….
The main characteristic is that it is continuing and valid for every place and time. Therefore in every era we can find a miracle of the Qur’an which is compatible with the science at that time. Nowadays, we are living in the era of the digital technology, what is the miracle that fits our era?!
An atheist made a try to fill hearts of Muslims with doubts about the creation of Adam and Jesus peace be upon them and he claimed that the Qur’an contains many myths and legends.
Is it possible to think that Allah Almighty may leave people without He puts all proofs in front of them that Qur’an is a divine book which contains a lot of miracles?
Let us contemplate at this wonderful numerical miracle!!! …
This is a journey of faith through Creation of Human…Allah says: " and see how (Allah) originated the creation, ... During this journey of faith, we will look at the stages of human’s creation by using the taken photos by scientists in the twenty one century and to look attentively at these stages as God told us about it in the Qur’an fourteen century ago

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

Phenomenon of lightning
1. Phenomenon of lightning
Is a clear evidence that prophet Mohamed is sincere
“Peace be upon him”
Written by: ABDEL DAYEM AL KAHEEL
www.kaheel7.com
Translated by : Ahmed Adham
ahmed.adham.eg@gmail.com
2. Engineer Abduldaem Al-Kaheel is a researcher in
the Scientific Miracles of the Quran and Sunnah.
He is born in the city of Homs (Syria) in 1966 and
he is the author of more than twenty book and
thirty booklet and he memorize the entire holy
book of Qur’an. Through this research he presents
a new discovery in the purified prophetic Sunnah.
Biography
3. Prophet Mohamed peace be upon him says:
(don't you see that the lightning comes and
back in an eye blink).[Narrated by Muslim]
4. Summary of the Research
In this research we will see how prophet Mohamed talked
precisely about phases of lightning as there is a complete
conformance between his saying and recent discoveries
concerning the lightning as recent scientists found that the
lightning strike happens in a fractions of a second ! This
scientific fact was discovered by the use of an advanced
camera which is able to capture one thousand photo per
second. The question is who told our illiterate prophet this
scientific information 1400 years ago?
6. Lightning in ancient legends
For many years, people used to believe that lightning
is a holy event which is related to gods that punish
those people who disobey them. In the seventh century
when prophet Mohamed was living, people believed
that “Zeus” is the god of lightning ,at that time the
smartest man used to believe in these myths.
8. The first one to study this phenomenon
In the eighteenth century and after eleven centuries
from the time of prophet Mohamed, many scientists
started to study the phenomenon of lightning and the
one who made the initiative was professor “Franklin”
who used his famous kite when he connected it to a
metal wire and sent it up between the clouds, a strong
spark was released when the electricity moved through
the wire when it touched the ground!
9. Franklin is the first one who proved that
the lightning is an electric spark
1752
10. Simply, lightning is the meeting of
negative charges with positive charges
negative charges
positive charges
11. The knowledge about the lightning was rare till the end of
the twenty century when the scientists discovered the
digital camera as they became able to capture 1000 photo
per second which enabled them to understand some
secrets about the lightning but details still unknown!
A historical fact
12. The lightning needs special kind of clouds
during the thunder storms
The question is: where does the lightning happen ?
13. Lightning in numbers around the world
• There are 100 lightning strike per second .
• There are 8 million lightning strike every day.
• In America the lightning kills 100 person every year.
A satellite photo
14. Marvelous numbers!
• Temperature of the lightning beam is 30000 Celsius
so it is five times greater than the temperature on the
surface of sun!!
• The volt per beam is: 1000 million volt.
• Electricity is: 200 thousand ampere
15. A lightning flash at midnight
The above photo shows lightning flash at midnight , if you
exposed to that flash you may became a permanently or
temporally blind according to the distance between
you and the flash.
16. In a holy verse Allah Almighty describes what
happens in the sky as He says:(Or like a rainstorm
from the sky, wherein is darkness, thunder, and
lightning){Sûrat Al-Baqarah-the cow-verse19}.
And in the next verse He Almighty tells us how
the lightning flash may affects us as He says:(The
lightning almost snatches away their sight)
{Sûrat Al-Baqarah-the cow-verse20}.
Who told our prophet this scientific information?
17. The scientists are studying the lightning….how?
The scientists are choosing a perfect cloud to study ,time
of the lightning flash and the time between each phase as
those scientists believe that the lightning flash differs from
a cloud to another according to how far it is from the
ground, amount of electrical charges in the cloud and on
the ground ,temperature ,wind speed and humidity.
20. The lightning occurs in phases
The scientists discovered that the lightning occurs in
two main phases which are the crossing phase and
the returning phase, and they captured photos for
these two phases and said with certainty that the
lightning descends from the cloud and returns again!!
21. The first phase
A negative charge
descends from the cloud
toward the ground in
part of a second.
22. The second phase
The positive charge on
the ground meets with
that negative charge.
23. The third phase
As a result, a strong electric
spark generates and goes
toward the cloud.
24. The fourth phase
Here we can see the
returned electric charge
and that is the lightning
beam, all of these four
phases happens in 25
Millisecond.
A millisecond is a thousandth (1/1,000) of a second
27. After all of these scientific facts, we have to ask a
simple question: How did prophet Mohamed peace be
upon him deal with this complicated phenomenon?
was he affected by all of the different myths and
legends at that time?
28. This prophetic hadith contains many scientific signs!
Prophet Mohamed peace be upon him tells us that
the believers will pass quickly on” As-Sirāt” which is
the hair-narrow bridge that every person must pass
on day of resurrection to enter Paradise as he says:
(you will pass on As-Sirāt like the lightning) and in
the same hadith he says about the phenomenon of
the lightning :(don't you see that the lightning comes
and back in an eye blink) [Narrated by Muslim].
29. A sign that the speed of the lightning
is very high
Prophet Mohamed peace be upon him says : (you
will pass on As-Sirāt like the lightning) which is a
clear sign that the speed of lightning is very high
30. A sign that the lightning occurs
in phases
The prophet says: (don't you see that the lightning
comes and back) , here is a clear sign that the
lightning occurs in two main phases which are the
crossing phase and the returning phase exactly as
what recent scientists say about the lightning!!
31. A sign to the time of
the lightning
The prophet say that the lightning strike occurs:(in an
eye blink) ,from the scientific point of view that saying
is right because the eye blink takes only milliseconds.
33. Steve Goodman, a scientist in NASA says about the lightning:
“A lightning strike can heat the air in a fraction of a second. When air
is heated that quickly, it expands violently and then contracts, like an
explosion that happens in the blink of an eye.”
All of the above was summarized by prophet Mohamed in
just a few words by saying: “don't you see that the
lightning comes and back in an eye blink ”!!
[Steve Goodman, A Lightning Primer, www.nasa.gov]
Also he says : “the type of lightning NASA is researching occurs
within clouds, invisible to the naked eye by day. To properly
monitor this type of lightning takes special equipment like NASA's
Lightning Imaging Sensor, The sensor tracks worldwide lightning
strikes and their relationship to storm centers.”
34. The point of inimitability in the Hadith
This hadith is a clear evidence that prophet Mohamed
peace be upon him is sincere and he is a prophet from
Allah Almighty. Also the hadith preceded all scientific
researches as no one on earth in the seventh century
ever talked about lightning in that precision
