This may help you with your studies and you may ace the SAT exam. There is a download link to get your copy of the APP on your smartphone.
Here is a picture of the site in English and you can use other languages also. To type an equation you need to use the pertinent math problem you are interested in. It ranges from Pre_Algebra to Matrix Calculation.
Give it a try.
Good luck

This is an 'if' scenario but scary. What if a 15 Kilton nuclear bomb is dropped on Bengaluru. This is a simulation using the site below for a 15 Kiloton bomb.
This is the simulation for the largest Pakistani weapon (tested)

We are so very close that even oceans apart we are still close.
Three scientists one each from the USA, France, and Austria share the 2022 Noble Prize in Physics for their pioneering experiments in Quantum Information Science.

Their work will revolutionize Computing, cryptography, and teleporting information.
Recipients sharing the prize:
Alain Aspect
Université Paris-Saclay and École Polytechnique, Palaiseau, France
John F. Clauser of J.F. Clauser & Association,
Walnut Creek, CA, USA,
Anton Zeilinger
University of Vienna, Austria
Summary of work from the Noble Prize site:
"John Clauser developed John Bell’s ideas, leading to a practical experiment. When he took the measurements, they supported quantum mechanics by clearly violating a Bell inequality. This means that quantum mechanics cannot be replaced by a theory that uses hidden variables.
Some loopholes remained after John Clauser’s experiment. Alain Aspect developed the setup, using it in a way that closed an important loophole. He was able to switch the measurement settings after an entangled pair had left its source, so the setting that existed when they were emitted could not affect the result.
Using refined tools and long series of experiments, Anton Zeilinger started to use entangled quantum states. Among other things, his research group has demonstrated a phenomenon called quantum teleportation, which makes it possible to move a quantum state from one particle to one at a distance."

Food is the most essential thing. No one will dispute. Celebrate this day, October 16 by joining the organized events or organizing one by yourselves by using the FAO toolkit. At least share and watch the World Food Day promotional video in this post.
"Collective action across 150 countries worldwide is what makes World Food Day one of the most celebrated UN days of the UN calendar. Hundreds of events and outreach activities bring together governments, businesses, CSOs, the media, the public, and even youth. They promote worldwide awareness and action for those who suffer from hunger and for the need to ensure healthy diets for all, leaving no one behind."
"#WorldFoodDay 2022 is being marked in a year with multiple global challenges including the ongoing pandemic, conflict, climate change, rising prices, and international tensions. All of this is affecting global food security.
It’s time to work together and create a better, more sustainable future for all. Make #WorldFoodDay YOUR day. Join the call by organizing an event or activity or show how you are taking action by connecting with us online."

Creating large area clouds to reflect light to where it came from or to space could reduce global warming. Read the BBC link for more information. One suggested way is to spray a large amount of seawater into the atmosphere as shown in the picture below taken from the BBC link. They claim that the method is extremely cost-effective.
The problem that faces any large-scale modification is one of ethics. What if, it leads to other problems. It is known in many countries that improperly planned manipulation of water resources has led to either draughts or unusual inundations. I recently read an article that strongly correlates the average temperature rise in Bengaluru and the occurrences of inundations with urban development when several natural ponds and lakes were sacrificed by the builders to build high-rise apartments. The study covers several years of such abuse.
The originators of the above concept in the BBC article seem to be bugged by the problem of nozzle clogging used to spray seawater. This is probably a tractable problem.
There is enough evidence that plastics are better at not having corrosion problems compared to metals. How strong a plastic is needed? how fine a spray is needed? How soon the corrosion sets in are some of the things that need research. Special coatings can be used to modify corrosion characteristics.
