चंद्रयान-I enters Lunar orbit......

मैंने चाँद की गोलईयों को,

जान पूछ कर चुना,

मन लगता नही अब यहाँ,

मैं दूर जो ऊर चला!

में आज चाँद पर चला था!

में कल भी चला था,
में आज भी चला हूँ।
बस फर्क सिर्फ़ इतना है कि,
में आज चाँद पर चला था!

(My congratulations to the Chandrayaan-1)

NASA to Discuss Mission to Study Sun's Weakening Protective Bubble

GREENBELT, Md. -- NASA will hold a media teleconference on Friday, Oct. 17, at 1 p.m. EDT, to preview the Interstellar Boundary Explorer, or IBEX, mission. The spacecraft may confirm if the sun's protective bubble surrounding our solar system, called the heliosphere, is about to shrink and weaken. IBEX also will be the first spacecraft to image and map the dynamic interactions taking place where the hot solar wind slams into the cold expanse of space. The heliosphere acts as a shield for our solar system, warding off most of the galactic cosmic rays. Recent data indicate the solar wind's global pressure is the lowest seen since the beginning of the space age. IBEX is set to launch Oct. 19 from the Kwajalein Atoll, a part of the Marshall Islands in the Pacific Ocean. Panelists will be: - David McComas, IBEX principal investigator at Southwest Research Institute in San Antonio - Nathan Schwadron, co-investigator and IBEX Science Operations Center lead at Boston University - Stephen Fuselier, co-investigator and IBEX-Lo Sensor lead at Lockheed-Martin Advanced Technology Center in Palo Alto, Calif. - Eric Christian, program scientist at NASA Headquarters in Washington Reporters should call 1-888-323-5257 and use the passcode "IBEX" to participate in the teleconference. International media should call 1-415-228-4881. Supporting information for the briefing will be available at the start of the teleconference on the Web at:

Reverse Mathematical Objects!




Newton’s third law: For every reaction there is a reaction, this is a Universal law! Today I will try to prove it mathematically. But still I am not sure of that how it exactly will be applicable practically. During normal thinking hours some seconds proved to be useful and productive which I would like to share with you through my blog! Only the great Almighty knows that whether I would be able to solve the riddle of life or not in my life time. May the Almighty enlighten me!
First draw a circle on x and y axis:-

Here we are analyzing that how the points on the perimeter of the circle behave wrt x and y coordinates! We start from (r,0) and finishes at (r,0) after taking a full anti-clockwise round. Here we intend to analyze the points on perimeter from minimum to maximum wrt to x and y coordinates.
Tabulating this:-


Now if we try to draw the points on any axis as (Min,Max) from first quadrangle to IV quadrangle then we find the flow of the coordinates as Clockwise.
Initially we have drawn the circle in a anticlockwise direction or we have drawn the circle from minimum to maximum in anticlockwise direction. But during mathematical analysis we found that minimum to maximum wrt to any of the coordinates do lies in clockwise direction. It is very interesting to note here that there exists a mathematical drama(U-Turn) here. It may be a reality too!
The same will apply to z and t axis also.
So, behind our every move it is proved at least mathematically that there exists a parallel negative factor also.
If we say the Universe is expanding then there would exist negative volumes also in the Universe. Or we also can’t deny the assumption that Universe is expanding with a rate of –dv/dt creating black holes if v is substantially almost equal to infinity or vice versa.
The derivation is quite simple but gives birth to a very interesting theory of “Reverse Mathematical Objects”.

Think when the Night is brighter than Day!

We know in a time-span of 24 hours there are altered sessions of day and night. Certain part of the world illuminates when it faces the bright Sun and the rest of the part sleeps in dark during the moment. Though the darker side is also not completely dark all the times in a month as it manages to get some lumen from the moon. Think for a possibility that if there is a star in the Universe which is probably brighter than the sun and can throw its rays to darker part of the earth and lighten the earth? Now you will say that the star would be billion light years far so it may take billions of years for this event to happen. It may be partly true but we can't reject the fact that the said star may on its way to complete its cycle might be nearing earth so the light may reach the earth in lesser billion years as assumed before. Well,this is one school of thought.
Now think if there is a star which is not a emitter of light but bigger in size than the star in the picture and it is right now blocking the path of the light emitting star. So, whenever this bigger star while moving unblocks the view of the illuminated star from the earth then the chances are there that the darker side of the earth which is not illuminated by the sun rays may get illumination from that particular star. And probably the lumen reaching the earth may be more than the lumen received from the sun so it can be concluded that the night can be brighter than the Day!

Doomsday 2012?

Apparently, the world is going to end on December 21st, 2012. Yes, you read correctly, in some way, shape or form, the Earth (or at least a large portion of humans on the planet) will cease to exist. Stop planning your careers, don't bother buying a house, and be sure to spend the last years of your life doing something you always wanted to do but never had the time. Now you have the time, four years of time, to enjoy yourselves before… the end.
So what is all this crazy talk? We've all heard these doomsday predictions before, we're still here, and the planet is still here, why is 2012 so important? Well, the Mayan calendar stops at the end of the year 2012, churning up all sorts of religious, scientific, astrological and historic reasons why this calendar foretells the end of life as we know it. The Mayan Prophecy is gaining strength and appears to be worrying people in all areas of society. Forget Nostradamus, forget the Y2K bug, forget the credit crunch, this event is predicted to be huge and many wholeheartedly believe this is going to happen for real. Planet X could even be making a comeback.
For all those 2012 Mayan Prophecy believers out there, I have bad news. There is going to be no doomsday event in 2012, and here's why…
The Mayan CalendarSo what is the Mayan Calendar? The calendar was constructed by an advanced civilization called the Mayans around 250-900 AD. Evidence for the Maya empire stretches around most parts of the southern states of Mexico and reaches down to the current geological locations of Guatemala, Belize, El Salvador and some of Honduras. The people living in Mayan society exhibited very advanced written skills and had an amazing ability when constructing cities and urban planning. The Mayans are probably most famous for their pyramids and other intricate and grand buildings. The people of Maya had a huge impact on Central American culture, not just within their civilization, but with other indigenous populations in the region. Significant numbers of Mayans still live today, continuing their age-old traditions.
The Mayans used many different calendars and viewed time as a meshing of spiritual cycles. While the calendars had practical uses, such as social, agricultural, commercial and administrative tasks, there was a very heavy religious element. Each day had a patron spirit, signifying that each day had specific use. This contrasts greatly with our modern Gregorian calendar which primarily sets the administrative, social and economic dates.

Most of the Mayan calendars were short. The Tzolk'in calendar lasted for 260 days and the Haab' approximated the solar year of 365 days. The Mayans then combined both the Tzolk'in and the Haab' to form the "Calendar Round", a cycle lasting 52 Haab's (around 52 years, or the approximate length of a generation). Within the Calendar Round were the trecena (13 day cycle) and the veintena (20 day cycle). Obviously, this system would only be of use when considering the 18,980 unique days over the course of 52 years. In addition to these systems, the Mayans also had the "Venus Cycle". Being keen and highly accurate astronomers they formed a calendar based on the location of Venus in the night sky. It's also possible they did the same with the other planets in the Solar System.
Using the Calendar Round is great if you simply wanted to remember the date of your birthday or significant religious periods, but what about recording history? There was no way to record a date older than 52 years.
The end of the Long Count = the end of the Earth?The Mayans had a solution. Using an innovative method, they were able to expand on the 52 year Calendar Round. Up to this point, the Mayan Calendar may have sounded a little archaic - after all, it was possibly based on religious belief, the menstrual cycle, mathematical calculations using the numbers 13 and 20 as the base units and a heavy mix of astrological myth. The only principal correlation with the modern calendar is the Haab' that recognised there were 365 days in one solar year (it's not clear whether the Mayans accounted for leap years). The answer to a longer calendar could be found in the "Long Count", a calendar lasting 5126 years.
I'm personally very impressed with this dating system. For starters, it is numerically predictable and it can accurately pinpoint historical dates. However, it depends on a base unit of 20 (where modern calendars use a base unit of 10). So how does this work?

The base year for the Mayan Long Count starts at "0.0.0.0.0". Each zero goes from 0-19 and each represent a tally of Mayan days. So, for example, the first day in the Long Count is denoted as 0.0.0.0.1. On the 19th day we'll have 0.0.0.0.19, on the 20th day it goes up one level and we'll have 0.0.0.1.0. This count continues until 0.0.1.0.0 (about one year), 0.1.0.0.0 (about 20 years) and 1.0.0.0.0 (about 400 years). Therefore, if I pick an arbitrary date of 2.10.12.7.1, this represents the Mayan date of approximately 1012 years, 7 months and 1 day.
This is all very interesting, but what has this got to do with the end of the world? The Mayan Prophecy is wholly based on the assumption that something bad is going to happen when the Mayan Long Count calendar runs out. Experts are divided as to when the Long Count ends, but as the Maya used the numbers of 13 and 20 at the root of their numerical systems, the last day could occur on 13.0.0.0.0. When does this happen? Well, 13.0.0.0.0 represents 5126 years and the Long Count started on 0.0.0.0.0, which corresponds to the modern date of August 11th 3114 BC. Have you seen the problem yet? The Mayan Long Count ends 5126 years later on December 21st, 2012.
DoomsdayWhen something ends (even something as innocent as an ancient calendar), people seem to think up the most extreme possibilities for the end of civilization as we know it. A brief scan of the internet will pull up the most popular to some very weird ways that we will, with little logical thought, be wiped off the face of the planet. Archaeologists and mythologists on the other hand believe that the Mayans predicted an age of enlightenment when 13.0.0.0.0 comes around; there isn't actually much evidence to suggest doomsday will strike. If anything, the Mayans predict a religious miracle, not anything sinister.
Myths are abound and seem to be fuelling movie storylines. It looks like the new Indiana Jones and the Kingdom of the Crystal Skull is even based around the Mayan myth that 13 crystal skulls can save humanity from certain doom. This myth says that if the 13 ancient skulls are not brought together at the right time, the Earth will be knocked off its axis. This might be a great plotline for blockbuster movies, but it also highlights the hype that can be stirred, lighting up religious, scientific and not-so-scientific ideas that the world is doomed.

Some of the most popular space-based threats to the Earth and mankind focus on Planet X wiping most life off the planet, meteorite impacts, black holes, killer solar flares, Gamma Ray Bursts from star systems, a rapid ice age and a polar (magnetic) shift. There is so much evidence against these things happening in 2012, it's shocking just how much of a following they have generated. Each of the above "threats" needs their own devoted article as to why there is no hard evidence to support the hype.
But the fact remains, the Mayan Doomsday Prophecy is purely based on a calendar which we believe hasn't been designed to calculate dates beyond 2012. Mayan archaeo-astronomers are even in debate as to whether the Long Count is designed to be reset to 0.0.0.0.0 after 13.0.0.0.0, or whether the calendar simply continues to 20.0.0.0.0 (approximately 8000 AD) and then reset. As Karl Kruszelnicki brilliantly writes:
"…when a calendar comes to the end of a cycle, it just rolls over into the next cycle. In our Western society, every year 31 December is followed, not by the End of the World, but by 1 January. So 13.0.0.0.0 in the Mayan calendar will be followed by 0.0.0.0.1 - or good-ol' 22 December 2012, with only a few shopping days left to Christmas." - Excerpt from Dr Karl's "Great Moments in Science".
