Nuclear physics is a branch of physics that focuses on the study of atomic nuclei and their interactions. It explores the properties and behavior of atomic nuclei, which are the central cores of atoms containing protons and neutrons. This field is crucial for understanding the fundamental forces that govern the behavior of matter at the atomic and subatomic levels.

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.

This presentation provides a briefing on how to upload submissions and documents in Google Classroom. It was prepared as part of an orientation for new Sainik School in-service teacher trainees. As a training officer, my goal is to ensure that you are comfortable and proficient with this essential tool for managing assignments and fostering student engagement.
2. HISTORY:
Hahn & Strassman
Meitner & Frisch
In 1939 They First Identified the nuclear fission.
Explained Hahn & Strassman results.
Instead of heavier Uranium , it had split into smaller
elements = Nuclear Fission.
Their Statement Was :
Bombarded Uranium -235 samples with neutrons expecting
the Uranium – 235 to capture neutrons.
4. NUCLEAR FISSION
A reaction in which an atomic nucleus of
a radioactive element splits by
bombardment from an external source ,
with simultaneous release of large
amount of energy , used for electric
power generation.
5. CHAIN REACTION
A chain reaction occurs when a
critical mass of uranium
undergoes fission .
Releasing a large amount of heat
and energy that produces an
atomic explosion.
7. ENERGY FROM FISSION
Each uranium-235 atom ha a mass of
3.9014 x 10-25 kg.
The total number of atom in 1kg of
uranium-235 can be found as follows:
No. of atoms in 1kg of uranium-235 =
1/3.9014 x 10-25 .
No. of atoms in 1kg of uranium-235 = 2.5 x
10-24 atom.
8. ENERGY FROM FISSION
If one uranium-235 atom undergoes a fission
reaction and release 2.385 x 10-11 J of energy , then
the amount of energy released by 1 kg of uranium-
235 aca be calculated as follows:
Total energy per fission x number of atoms
Total energy = 2.385 x 10-11x 2.56 x 1024
Total energy = 6.1056 x 10 13 J
9. NUCLEAR POWER PLANT
In nuclear power plants:
Fission is used to produces energy.
Control rods in the reactor absorb
neutrons to slow and control the
chain reactions of fission.
10. FISSION CAN BE USED:
GOOD
A controlled chain reaction in a reactor used
in nuclear power plant to produce electricity.
EVIL
An uncontrolled chain reaction is used to
create incredibly powerful weapons – the atomic
bombs dropped on Japan.
11. NUCLEAR FUSION
Nuclear fusion is the process by which multiple
nuclei joins together to form a heavier nucleus.
It is accompanied by the release or absorption of
energy depending on the masses of the nuclei
involved.
2H + 3H 4He + 1n + Energy
1 1 2 0
12. FUSION : SMALL NUCLEI FROM LARGER
NUCLIDE , RELEASE ENERGY
13. ENERGY FROM FUSION
2H + 3H 4He + 1n + Energy
1 1 2 0
m = 3.1 x 10-29 Kg E = mc2
C = 3x 108 ms-1 E = 3.1 x 10-29 x (3 x 108)2
E = E E = 2.79 x 10 -12 J
The energy released per fusion is 2.79 x 10-12 J.
14. FUSION CAN BE USED
GOOD
A controlled reaction in a reactor used to
produce cleaner , inexpensive electricity.
EVIL
A fission bomb starts a fusion chain reaction to
create an incredibly powerful weapon –
thermonuclear weapons (H-bombs), MUCH more
destructive than atomic bombs.
