Online lecture assignments for XI Sc

Hello Programmers,
To use this medium effectively, refresh this page every 10 min or so for as long as the lecture is in session, since I will update this post time and again. You can also try coming in on NetMeeting (if that works) by reading the instructions on our web.

Here you go:
  1. Given three numbers a, b & c you can find out which is the largest of them by comparing each number with the others in turn. Can you do this in a program? The logic goes like this:
  1. 1. Take a, b, c from the user
  2. 2. Is a > b and c ... then a is largest
  3. 3. Is b > a and c ... then b is largest
  4. 4. If none of the above, then c is largest
Now what will you do if you need to find the largest among say a 100 numbers??? Can the same logic work?
Using arrays makes life better while computing large data. So try this logic
  1. Take the numbers as inputs into an array having an appropriate size, say 'n'
  2. define an arbitrary high value - max - maybe 0
  3. Run loop from 0 to n
  4. In each iteration, check if the i'th element of the array is larger than max
  5. If the ith element is bigger than max, change the value of max to the ith element
  6. at the end of the loop you get your value in max
Will give you more assignments with arrays and using the File commands by the evening. Try them over the weekend.

Annual Day 2023

 After a long hiatus due to covid we finally got most activities on track. The Annual Day function is always a big deal for everyone at Abhinav. It has been a tradition my mother started that the Annual Day will be not a Teacher-managed event, but a Student Initiative. Since when I was a teenager, I was part of this and today 10 years after she passed, I still strive to make it work as she would have. After some hesitation, we began working in early January. I wanted to use an outside choreographer just so that teachers will not be burdened. (They are already struggling with post-covid learning difficulties) But then, an outside guy could never do justice to the Abhinav style of doing things. We always keep in mind that the cultural program should be enjoyable to everyone in the audience and at the same time should display as many of the diverse talents that our students have, as possible.  It was a great relief that my G3 students came to the rescue. Almost all of std 9 and many of st

Are Self-Driving Cars Taking Over Humans?

- Arya Dharmadhikari(Std X, Abhinav Vidyalay) The 21st century has played an important role in the advancement of technologies. This development has even revolutionized the Automobile industry. We have developed from fuel-efficient vehicles to Hybrids and EVs and now we are enhancing self-driving vehicles. Tesla, Waymo, Volvo, GM, BMW, Mercedes are among the few companies that have started testing self-driving cars. The leading among them is Waymo, which has developed level 4 autonomy which we will discuss in the next section. So before reaching levels of autonomy we should understand what self-driving cars are and why we require them. What is a self-driving car? A self-driving car (also called an autonomous vehicle) is a car that is competent in driving itself without any human intervention. The car has sensors, cameras, lasers, radars, GPS, LIDAR through which the Artificial Intelligence senses the surrounding environment, this helps the car to navigate on its path and to detect sig

Dark Matter

  ~Anvi Patil(X th A Abhinav Vidyalay) In the universe, there is about 25% of dark matter and 70% of dark energy but only 5% of it is visible. What is Dark Matter? It is a non-luminous material, which holds two galaxies. This cannot be called a black hole because it does not bend light. Then the question arrives, as it is non-luminous, how did we detect it? As it is not visible, scientists have found indirect methods to find more about it. One such method is by using the Fermi Gamma-Ray Space Telescope . Gamma rays are released when two particles of dark matter collide, Fermi telescope can be used to detect this collision. This topic was discovered by Fritz Zwicky in the 1930s, he discovered that galaxies were rotating at a faster rate than usual. A dark region seen in the foreground of a star field. This dark region could be a dark cloud of gases like hydrogen, left over from the formation of our galaxy Dark matter is called ‘dark’ not because it is ‘black’ but because it does not
