This document discusses how light travels faster than sound and provides examples. It notes that light travels around 300,000 km/s, which would allow it to circle the world 8 times in 1 second. The document also discusses the electromagnetic spectrum and visible light. It explains that white light is made up of the seven colors of the rainbow - red, orange, yellow, green, blue, indigo, and violet - and how a prism can split white light to demonstrate this.

What is the purpose of the Sabbath Law in the Torah. It is interesting to compare how the context of the law shifts from Exodus to Deuteronomy. Who gets to rest, and why?
2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.
This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.

How to Make a Field invisible in Odoo 17Celine George
It is possible to hide or invisible some fields in odoo. Commonly using “invisible” attribute in the field definition to invisible the fields. This slide will show how to make a field invisible in odoo 17.

2. Light travels much faster than sound.
For example:
1) Thunder and lightning start
at the same time, but we will
see the lightning first.
2) When a starting pistol is
fired we see the smoke first
and then hear the bang.
3. Light travels VERY FAST –
about 300,000 kilometers per
second or 186,000 miles per
second.
At this speed light
could travel the
equivalent of 8
times around the
world in one second!
5. Remember radio waves are long…
…and gamma rays are small
Radio-TV -Microwave- Infrared – VISIBLE -Ultraviolet -X- rays - Gamma- Cosmic
6. *Electromagnetic Radiation
Electromagnetic radiation can be described
in terms of a stream of photons. Each
photon is traveling in a wave-like pattern,
moving at the speed of light and carrying
some amount of energy.
7. Color
White light is not a single color; it is made up of a
mixture of the SEVEN colors of the rainbow.
We can demonstrate this
by splitting white light
with a prism:
This is how rainbows are
formed: sunlight is “split
up” by raindrops.
8. The colors of the rainbow:
Red
Orange
Yellow
Green
Blue
Indigo
Violet
Just remember ROY G. BIV
The only difference amongst radio waves, visible light, and gamma-rays is the amount of energy of the photons. Radio waves have photons with low energies. Microwaves have a little more energy than radio waves. Infrared has still more energy.
As we move down the chart we see visible, ultraviolet, X-rays, and gamma-rays whose photon energies gradually increase.
Gamma and Cosmic rays have the highest energy waves.
