### Three for the day

Three questions today (you will know why tomorrow :) )

1. Guest question from Rogi

Why are you seeing these on BB today? (See post date, not today’s date :) )

2. Guest question from p vs np. Yes, this question _had_ to come from him :)

Identify 1. and his recent claim to fame.

Though his claim is under intense scrutiny, if proved, he shall join ranks with 2. and shall gain eternal fame in the Kingdom of Nerds.

3. “Fan” proposed icon for what?

One point per correct answer, run-length intact if you get at least one right.

P.S: We have a huge queue of guest questions in our inbox. If you sent one, please stay tuned, it will make it to the main page soon :)

Cracked by: **Logik(2) ** , sandesh(2) , Manish Achuth(3) , p vs np(3) , Ananth(2) , Anjul(2) , Dibyo(3) , Raghuvansh(2) , krudebox(3) , Girish(2) , Rogi(3) , Bheema V(2) , Rahulk(2) , Sumanth Patlolla(2) , Ganesh Prasad(3) , dheeraj(2) , Rahul Rajeev(2) , shrik(3) , blntechie(2) , Thejas V R(3) , Bharath(2) , Jean Valjean(2) , Vinay Hegde(3) , lanu(3) , Qbrain(3) and Shwetha Maiya(3)

Answer:

Rogi’s answer for 1 – Echo One, the Space Shuttle Enterprise and the Mars Reconnaissance Orbiter were all launched or had their maiden flight on August 12th.

p vs np’s answer for 2 – That’s Vinay Deolalikar, an HP Labs researcher who’s recently published a manuscript asserting P != NP (and thankfully, not otherwise).

He’s provided a proof to the million dollar worth P vs NP problem.

If proved right, he shall join ranks with Gregory Perelman, who recently solved the Poincare Conjuncture

3: Fan proposed ‘Meh’ button to disapprove social network atrocities. Its the opposite of “Like” on Facebook.

1. Friday 13th space disasters.

Russian communication satellite with u.s iridium.

Apollo 13th launch failure.

2. vinay deolalikar , grigori perelman.

pvsnp problem solution.

3. meh instead of a facebook ‘dis’like button

1. 50 years of sat commn

2. Toughest math problem solver – Vinay Deolalikar

3. Dislike symbol on FB

1. All launched on August 12th. Echo1, Space shuttle Enterprise and Mars Reconnaissance Orbiter.

2. Millennium Problem solvers. Vinay Deolalikar and Grigori Perelman.

3. Proposed facebook icon for “meh” as opposed to Like.

1. Aug 12 – Enterprise’s first flight. 13th – Echo1 implemented. 20th – Viking takes a trip. Quite a few things done in August over a range of years, apparently.

2. That’s Vinay Deolalikar, an HP Labs researcher who’s recently published a manuscript asserting P != NP (and thankfully, not otherwise).

He’s provided a proof to the million dollar worth P vs NP problem.

If proved right, he shall join ranks with Gregory Perelman, who recently solved the Poincare Conjuncture.

PS:

I’ll miss my BB handle :-|

3. An FB fan proposed symbol for ‘Meh’, existing Like’s anti-thesis. As if there wasn’t enough junk on it already..

Well, thats the Mars Reco Orbiter and not the Viking. And apparently that too was launched on the 12th. Quite a few firsts on the 12th of August.

1)

a) 1960 – Echo 1A, NASA’s first successful communications satellite, is launched.

c)Aug. 12, 2005 – NASA’s Mars Reconnaissance Orbiter, or MRO, launched

c) Aug 12, 1977 – The first free flight of the Space Shuttle Enterprise.

2) Vinay Deolalikar (HP) has claimed he has proved P != NP. The proof is under scrutiny. G. Perelman solved Poincare Conjecture. Both are millenium prize questions.

3)

I know (1) but I googled it so don’t consider it.

(2) is Vinay Deolalikar who claims to have proven P!=NP. His proof is being considered by experts these days (and as of now seems to have some potential flaws). He might join this other dude who received (and I think rejected?) the millenium prize for proving the poincaire conjecture.

(3) Is that the meh icon being considered for facebook posts where you don’t have much of an opinion? I saw this on Failblog a few days ago.

1. all launched on aug 12 by nasa, echo 1, enterprise and mars orbiter

2. deolikar and his proof of the pnp problem – the other pic is perelman

3. meh on the facebook, as in like, but meh

1. 50th anniversary of Echo 1, NASA’s first communications satellite

2. Vinay Deolalikar. P!=NP. Really, now, is this BB-standard? :)

3. Facebook ‘meh’, the opposite (or something) of ‘like’.

1. Launches made on Aug 12 in history.

1960 – Echo 1 launch, first passive communications satellite launched by NASA

2005 – MRO (Mars Reconnaissance Orbiter) launch

2. Mr.Vinay Deolalikar of HP laboratories claims to have solved the p vs np problem.

3. Facebook for ‘Dislike’ button or to express your apathy.

1- the planets – Mercury, Saturn, Venus and Mars – line were aligned on that day.

2- Vinay deolikar claims to prove a clay prize for mathematics problem P=NP, he wiil join gregory perelman who prove another clay prize for maths problem “poincare conjuncture”

3- Don’t know

1 – Echo One, the Space Shuttle Enterprise and the Mars Reconnaissance Orbiter were all launched or had their maiden flight on August 12th.

2 – Grigori Perelman(2) Won the first Clay Millennium Prize for proving The Poincaré conjecture

Vinay Deolalikar(1) has distributed a proof that P ? NP and if so, will be the 2nd CMP recipient of 7, total and may make some of the other 5 fall, soon..

3 – A “Meh” button for Facebook

Please ignore earlier comment

1- the planets – Mercury, Saturn, Venus and Mars – line were aligned on that day.

2- Vinay deolikar claims to prove a clay prize for mathematics problem P=NP, he wiil join gregory perelman who prove another clay prize for maths problem “poincare conjuncture”

3- This proposed Facebook button would allow your online friends to know right away that you don’t care.

1. First (possibly orbital) flights of US communication satellite, Space Shuttle, and some other space vehicle thingie.

2. Vinay Deolalikar (hope I got that correct) with his proposed proof of P=/=NP, could join G. Perelman of Poincare proof fame.

3. Icon for ‘Meh’ button on facebook.

(1)

(a) Stamp commerating Echo 1

(b) Space Shuttle Enterprise

(c) MRO — Mars Reconnaissance Orbiter

12th August , 2005 was the launch date for MRO

Connect is maybe first in its type of mission

(2)

(a) Vinay Deolalikar

(b) Grigori Perelman

(a) claims to have found a solution to one of the famous open problem in Mathematics(also a Millenium Prize open problem) i.e. p vs np… In case his claim is proved he will join the ranks of (b) who is already a winner in Millenium prize for his works on Poincare Conjecture

(3) This is a fan proposed icon for “meh” as opposed to like in Facebook

1) On August 12, 1918, the Unites States Post Office Department took over air mail service from the U.S. Army Air Service (USAAS).

On August 12, 1977, the Space Shuttle Enterprise flew on its own for the first time.

On August 12, 2005,Mars Reconnaissance Orbiter (MRO) was launched aboard an Atlas V-401 rocket from Space Launch Complex 41 at Cape Canaveral Air Force Station.

2) Vinay Deolalikar,an Indian computer scientist,sent a manuscript to various leading researchers claiming to contain a proof that P ≠ NP, a Clay Mathematics Institute Millennium Prize Problem and one of the most important open problems in mathematics and computer science.

3)Facebook ‘Meh’ button proposed to express disgust or to say “I dont care”

1. Boiled Beans is entering its 4th year ?

2. Vinay deolalikar who claims that he has proved P!=NP

3. proposed Facebook icon to express disagreement or indifference(opposed to like)

Re-answering (1):

On this day –

(i)1960 – Echo 1A, NASA’s first successful communications satellite, is launched for which the U.S. Post office issued a postage stamp commemorating the same on December 15, 1960

(ii)1977 – The first free flight of the Space Shuttle Enterprise.

1>

NASA’s first successful communications satellite, is launched.

The first free flight of the Space Shuttle Enterprise.

Mars Reconnaissance Orbiter launched on August 12th

2>

Vinay Deolalikar who has proposed the solution for p vs np problem.

facebook

1.August 12th was the 50th anniversary of the launch of the first communication satellite, the ‘ECHO 1’ shown in the stamp

2. 1- Vinay Deolalikar

2- Grigori Perelman

1. The Echo 1 – first ever comms satellite – was put into orbit ‘this day’ in 1960

2. Vinay Deolalikar claims to have cracked p_vs_np. Might be only second person to land the Millenium prize after Grigori Perelman cracked the Poincare Conjecture.

3. A Facebook “meh” button a la “Like”.

1. Anything with Meteor showers? Don’t know this one.

2. Vinay Deolalikar. Published(?) a proof for P NP

3. “Meh” button – works opposite to “Like” button of Facebook

1. MRO and Echo 1 were launched on Aug 12th. So was BB. :)

2. Vinay Deolalikar and his p != np proof. If his proof is right, he will be the second recipient of the Clay Millennium Prize problem award.

3. Meh button for facebook. I ‘like’. :)

2. Vinay Deolalikar from HP who claims to have solved the p vs np problem , one of the seven problems posed by the clay mathematical institute… the 2nd pic is that of grigori perelman who solved the poincare conjecture….

1. The first communications satellite was put in space on August 12th.

2. Vinay Deolalikar – possible P/NP proof and Perelman – Poincare Conjucture proof. Connect: Millennium prize problem solvers.

3. The ‘meh’ button for posts like the ‘like’ button on Facebook.

1. It was on 12th August that the events portrayed in the pics happened.

a. The Echo I communications satellite, 1960.

b. The first free flight of Space Shuttle Enterprise, 1977.

2. Vinay Deolalikar, the P!=NP supposed proof. Grigori Perelman of course famous for his Poincare Conjecture proof and his eccentricity.

3. The proposed ‘Meh’ button for facebook symbolizing apathy or not interesting.

1. World’s first communication satellite, MRO was launched on Aug 12th,1960.The stamp(pic 1) was produced and issued to honor the world’s first communications satellite. Space Shuttle Enterprise(Pic 2)flew on its own for the first time on Aug 12th , 1977 and Mars Reconnaissance Orbiter (pic 3) was launched on Aug 12th , 2005.

2.Vinay Deolalikar(pic 1), a scientist at HP has proposed a possible proof for the famed P=NP problem in mathematics—a feat that could net him $1 million for solving one of the seven Clay Mathematics Institute Millennium Problems. One of the seven problems that had $1 million Clay prizes was solved by Grigori Perelman(pic 2).

3.Facebook ‘Meh’ button.Todd Greene is the creator of the button.

Question 1:

1st pic is Stamp of US celebrating the launch of “worlds first communications satellite” launched on August 12th.1960

2nd pic is “Space Shuttle Enterprise”. On August 12, 1977, it flew on its own for the first time

3rd pic is “Mars Reconnaisance Orbiter” was launched August 12, 2005

All events on August 12th.

Question 2:

Pic 1 is “Vinay Deolalikar”, a research scientist at HP Labs. He claims to have solved as an independent researcher the most famous unsolved problem in complexity theory “P = NP.” this is one the seven problem of the “Millienium Prize Problems”. The only one of the seven, that is solved till today is by “Grigori Perelman” in Pic 2

Question 3:

A “Meh” button design for Facebook to help express your apathy

1. Vintage 1960 Stamp Communications for Peace – Postmaster General Arthur E. Summerfield on November 10, 1960, announced plans to issue a 4-cent stamp on December 15, 1960, at Washington, D.C., commemorating Echo I — the world’s first passive communications satellite — placed in orbit around the earth by the National Aeronautics and Space Administration on August 12, 1960

Mars Reconnaissance Orbiter – was launched August 12, 2005
