Who was the first choice to play the role of Tezaab in the film of the same name?

 It’s said and even Aditya Pancholi had claimed that he was the first choice for Teezab. According to sources, N. Chandra had narrated the film to Aditya Pancholi who loved it and was ready to sign the film.

Few weeks later, he came to know that Anil Kapoor was roped in due to the influence of Boney Kapoor. Pancholi had hinted about the “favouritism” and ”politics” that takes place in Bollywood. He also stated that the same could be verified by director, N. Chandra.

However, some sources from the production team refuted these claims. According to them, the film was built entirely around Anil Kapoor, who was already an established star at that time.

For the female lead Meenakshi Seshadri was the original choice but was replaced by Madhuri Dixit due to payment matters and date issues.

Tezaab was a watershed moment in Anil Kapoor's career cementing his status as a top -tier superstar after Mr. India.

It was also a pivotal film in Madhuri Dixit's career propelling her to stardom. The film ran in theatres for more than 50 weeks. Also, it was N. Chandra's hat-trick at the box-office after the success of Ankush (1986) and Pratighaat (1987).

Which is the first Hindi movie of Bollywood?

 The first full-length Hindi feature film in what is now called Bollywood is:

Raja Harishchandra (1913)

It was directed by Dadasaheb Phalke, who is widely regarded as the “father of Indian cinema.”

---

Key facts about Raja Harishchandra:

• Release year: 1913
• Format: Silent film (no recorded dialogue)
• Language: No spoken language, but based on Indian mythological story (later associated with Hindi cinema history)
• Director: Dadasaheb Phalke
• Theme: Story of King Harishchandra, known for truthfulness in Hindu mythology
• Length: About 40–50 minutes (varies by restored versions)

---

Why it is considered the first Bollywood film

Even though the term “Bollywood” did not exist at the time, Raja Harishchandra is recognized because:

• It was the first Indian-made full-length narrative feature film
• It marked the beginning of commercial cinema production in India
• It established storytelling techniques later adopted by Hindi cinema

---

Important context

• The film was silent; sound films in India started much later with Alam Ara
• “Bollywood” as a term became common only in the later 20th century, referring specifically to Hindi-language commercial cinema based in Mumbai

---

Conclusion

The first Hindi cinema foundation is generally traced to Raja Harishchandra (1913) by Dadasaheb Phalke, which marks the beginning of Indian feature filmmaking and the historical origin of Bollywood.

What was the very first mathematical fact you learned that blew your mind?

 The Ramanujan Summation: 1 + 2 + 3 + ⋯ + ∞ = -1/12.

When I was first told by my friend about this, I was just blown away. I thought he is joking around, but then I got to know that this is real. Then I thought that most of the scientists must have rejected this, but no. I was wrong, it is even used in higher physics.

This was and is one of the most mind blowing mathematical facts that I came to know.

It is amazing how each positive numbers are added and the result you get is negative.

Here's the prove which is even more interesting.

The prove given below is just for fun and it is not valid. So if you want to enjoy then only read and if you are a mathematician then please don't read.

Consider

S1= 1-1+1-1+1-1+1-1…..

Now, this sum should be 0 or 1 based on number of natural numbers taken. If infinite numbers are even, S1=0, if odd then S1=1. But, Riemann zeta function gives it a value of ½. Mathematical community too agrees that the sum is ½.

Let

S2=1-2+3-4+5-6+7…..

So, S2=1-2+3-4+5-6+7-8+9…..

S2= 1-2+3-4+5-6+7-8……. I have shifted RHS by a unit position

+2S2=1-1+1-1+1-1+1…..

Hence, 2S2=S1

Therefore, S2=1/4

Let’s come back to our sum of infinite numbers.

S=1+2+3+4+5+6+7+8+9…..

S2=1-2+3-4+5-6+7-8+9….

S-S2=4+8+12+16+20…..

Hence,

S-S2=4(1+2+3+4+5+6+7+8….)

S-S2=4S

So, -S2=3S

And, S = -S2/3 = -1/12

This shocking result is not known to many non-mathematicians. Number-theorists call it “One of the most remarkable formulae in science”. This summation is a secret of mathematics kept away from layman. Further, it is interesting to know ‘S’=-1/12 has been used to derive the equations in “string theory”, quantum field theory and in some complex analytics.

EDIT: here is a new proof for all mathematicians:

I have given the following propositions. If you want a prove of that the please comment.

Proposition 1.

(2.1)

Proposition 2.

(2.2)

We define the function Sn and Hn (x) as follows.

(2.3)

(2.4)

Then we define the following symbols.

(2.5)

(2.6)

(2.7)

(2.8)

Then we have the following propositions.

(2.9)

(2.10)

(2.11)

The double quotes mean the analytic continuation of the sum of natural numbers.

The traditional sum diverges for the infinite terms. On the other hand, the new “sum” is equal to the traditional sum for the finite term. In addition, the “sum” converges on -1/12 for the infinite term.

What is India's first driverless metro train?

 India's first driverless metro was started from Delhi operating on the 37-kilometer long Magenta Line between Janakpuri West and Botanical Garden and inaugurated by Prime Minister Narendra Modi on 28th December 2020,

Technology were used in train, Communication-Based Train Control (CBTC) and GoA 4 (Grade of Automation 4) technology, allowing for automatic wake-up, operation, and diagnostics without train operator or motorman to efficiently run service smoothly.

Then in South India, Bangalore Metro train started operating with driverless technology from Bommasandra to RV Road via Silk Board Yellow Line, 3rd metro line after the violet and green line.

Which is the first movie of Paresh Rawal?

 Paresh Rawal made his debut with a Gujrati film titled Naseeb Ni Balihari in 1983. As far as Bollywood is concerned his first film was Hifazat - Life in Danger.

After doing one more not so popular film he was seen in Ketan Mehta’s, Holi which starred Aamir Khan, Om Puri, Naseeruddin Shah and Kittu Gidwani.

Further he was seen in films like Lorie, Arjun, Bhagwan Dada and Samundar. But the film which made him popular was the Mahesh Bhatt directed film Naam which starred Sunjay Dutt and Kumar Gaurav.

He playes an antagonist character named Rana. Though the character was negative there was a slight decency in his mannerisms and I can still remember his unique laughter in the film.

After Naam he mostly played negative roles later shifted to comedy genre and character roles. No doubt, Paresh Rawal’s performance in Naam surely finds a place in his top performances list. An actor par excellence.

Who was the first choice for Rishi Kapoor's role in the film "Chandni"?

 Govinda and Rekha were the first choice for Chandni, though Anil Kapoor was just considered for the same. The title, “Chandni” itself was the screen-name of Rekha in the film, “Silsila”. However Rekha refused the film. Coming back to the question.

Yash Chopra was going through a bad financial phase as his films were not clicking at that time. He wanted to make a present day romantic love story. Govinda was an emerging star at that time and Chopra narrated the story to Govinda.

Govinda straightaway rejected it as the film had a portion where the hero falls from a helicopter and has an accident due to which both his legs are damaged.

Govinda was not comfortable to play the part where he is disabled and is on a wheelchair. He did not want to play the role of a lame person.

Interestingly, it was a crucial part of the storyline and could not be changed. So he turned down the offer making way for Rishi Kapoor to romance Sridevi.
