Ten Things That Will Disappear In Our Lifetime

Ten Things That Will Disappear In Our Lifetime    

 
1. The Post Office

 
Get ready to imagine a world without the post office. They are so deeply in financial trouble that there is probably no way to sustain it long term. Email, Fed Ex, and UPS have just about wiped out the minimum revenue needed to keep the post office alive. Most of your mail every day is junk mail and bills.

 

 
2. The Check

 
Britain is already laying the groundwork to do away with check by 2018.  It costs the financial system billions of dollars a year to process checks.  Plastic cards and online transactions will lead to the eventual demise of the check.  This plays right into the death of the post office.  If you never paid your bills by mail and never received them by mail, the post office would absolutely go out of business.

 

 
3. The Newspaper

 
The younger generation simply doesn't read the newspaper.  They certainly don't subscribe to a daily delivered print edition.  That may go the way of the milkman and the laundry man.  As for reading the paper online, get ready to pay for it.  The rise in mobile Internet devices and e-readers has caused all the newspaper and magazine publishers to form an alliance.  They have met with Apple, Amazon, and the major cell     phone companies to develop a model for paid subscription services.

 

 
4. The Book

 
You say you will never give up the physical book that you hold in your hand and turn the literal pages  I said the same thing about downloading music from iTunes.  I wanted my hard copy CD.  But I quickly changed my mind when I discovered that I could get albums for half the price without ever leaving home to get the latest music.  The same thing will happen with books.  You can browse a bookstore online and even read a preview chapter before you buy.  And the price is less than half that of a real book.  And think of the convenience!  Once you start flicking your fingers on the screen instead of the book, you find that you are lost in the story, can't wait to see what happens next, and you forget that you're holding a gadget instead of a book.

 

 
5. The Land Line Telephone

 
Unless you have a large family and make a lot of local calls, you don't need it anymore.  Most people keep it simply because they've always had it.  But you are paying double charges for that extra service.  All the cell phone companies will let you call customers using the same cell provider for no charge against your minutes.

 

 
6. Music

 
This is one of the saddest parts of the change story.  The music industry is dying a slow death.  Not just because of illegal downloading.  It's the lack of innovative new music being given a chance to get to the people who would like to hear it.  Greed and corruption is the problem.  The record labels and the radio conglomerates are simply self-destructing  Over 40% of the music purchased today is "catalogue items," meaning traditional music that the public is familiar with.  Older established artists.  This is also true on the live concert circuit.  To explore this fascinating and disturbing topic further, check out the book, "Appetite for Self-Destruction" by Steve Knopper, and the video documentary, "Before the Music Dies."

 

 
7. Television Revenues

 
To the networks are down dramatically.  Not just because of the economy.  People are     watching TV and movies streamed from their computers.  And they're playing games and doing lots of other things that take up the time that used to be spent watching TV.  Prime time shows have degenerated down to lower than the lowest common denominator.  Cable rates are skyrocketing and commercials run about every 4 minutes and 30 seconds.  I say good riddance to most of it.  It's time for the cable companies to be put out of our misery.  Let the people choose what they want to watch      online and through Netflix.

 

 
8. The "Things" That You Own

 
Many of the very possessions that we used to own are still in our lives, but we may not actually own them in the future.  They may simply reside in "the cloud."  Today your computer has a hard drive and you store your pictures, music, movies, and documents.  Your software is on a CD or DVD, and you can always re-install it if need be.  But all of that is changing.  Apple, Microsoft, and Google are all finishing up their latest "cloud services."  That means that when you turn on a computer, the Internet will be built into the operating system.  So, Windows, Google, and the Mac OS will be tied straight into the Internet.  If you click an icon, it will open something in the Internet cloud.  If you save something, it will be saved to the cloud.  And you may pay a monthly subscription fee to the cloud provider.  In this virtual world, you can access your music or your books, or your whatever from any laptop or handheld device.  That's the good news.  But, will you actually own any of this "stuff" or will it all be able to disappear at any moment in a big "Poof?"  Will most of the things in our lives be disposable and whimsical?  It makes you want to run to the closet and pull out that     photo album, grab a book from the shelf, or open up a CD case and pull out the insert.

 

 
9. Joined Handwriting (Cursive Writing)

 
Already gone in some schools who no longer teach "joined handwriting" because nearly everything is done now on computers or keyboards of some type (pun not intended)

 

 
10. Privacy

 
If there ever was a concept that we can look back on nostalgically, it would be privacy.  That's gone.  It's been gone for a long time anyway..  There are cameras on the street, in most of the buildings, and even built into your computer and cell phone.  But you can be sure that 24/7, "They" know who you are and where you are, right down to the GPS coordinates, and the Google Street View.  If you buy something, your habit is put into a zillion profiles, and your ads will change to reflect those habits..  "They" will try to get you to buy something else.  Again and again and again.

 

 
All we will have left that which can't be changed.......are our "Memories".

Isro, Indian Railways to Sign MoU for Remote Sensing, GIS Technologies


Aiming at effective use of space technology in remote sensing and graphic information system (GIS) based applications, Railways is set to join hands with Indian Space Research Organisation (Isro).

An MoU will be signed between Railways and Isro, under Department of Space, tomorrow for developing applications in the field of remote sensing and GIS.

The MoU will enable use of space technology tools in providing passenger information for all trains, indicating next station/stoppage, real-time train-tracking, survey of new rail route alignments particularly in hilly and difficult terrains.

It will also aid in conducting track vulnerability studies, mapping of assets, audio-visual warning to road users at unmanned level crossing gates and introduction of web-enabled rail user-centric services.

Currently, Railways is using space technology for providing connectivity to Passenger Reservation System (PRS) counters and unreserved ticketing system at remote and non-rail head locations.

Besides this, the technology is used for emergency communication using satellite phones from disaster sites, Global Positioning System (GPS) for various applications like remote monitoring of locomotives, passenger information system in Mumbai suburban trains and synchronised clocks and Wi-Fi facility in select Rajdhani Express trains.

Isro to Launch Sixth Navigational Satellite on Thursday

India is slated to put into orbit its sixth navigation satellite on Thursday evening, the Indian Space Research Organisation (Isro) announced in Chennai on Monday.

The 1,425-kg IRNSS-1F - Indian Regional Navigation Satellite System-1F - would hurtle into space on board its Polar Satellite Launch Vehicle (PSLV) on March 10, the Isro said.


The rocket will blast off around 4pm from the spaceport at Sriharikota in Andhra Pradesh, about 80km from Chennai.

This will be already the second rocket launch for India in 2016. The first one was on January 20 when a PSLV rocket put into orbit the IRNSS-1E satellite in text-book style.

Till date India has launched five regional navigational satellites (IRNSS-1A, 1B, 1C, ID and 1E) as part of a constellation of seven satellites to provide accurate position information service to users across the country and the region, extending up to an area of 1,500km.

Though the full system comprises nine satellites -- seven in orbit and two on the ground as stand-by - the navigation services could be made operational with four satellites, Isro officials had said earlier.

Each satellite costs about Rs. 150 crores and the PSLV-XL version rocket costs about Rs. 130 crores. The seven rockets would entail an outlay of about Rs. 910 crores.

The entire IRNSS constellation of seven satellites is planned to be completed in 2016 itself.

The first satellite IRNSS-1A was launched in July 2013, the second IRNSS-1B in April 2014, the third on October 2014, the fourth in March 2015, and the fifth in January this year.

The seventh satellite IRNSS-1G is expected to be launched in the second half of 2016.

Once the regional navigation system is in place, India need not be dependent on other platforms.

Today first time Isro is Testing PSLV Multiple Burn Engine

The Indian space agency on Wednesday will be testing its ability to restart the fourth-stage engine of its rocket Polar Satellite Launch Vehicle (PSLV) on shutting it down after putting into orbit six Singaporean satellites.

Technically speaking, India will be testing its multiple burn fuel stage/rocket engine for the first time.

"The restart and shut off of the fourth stage engine is done as a first step towards launching multiple satellites but in different orbits," a senior official of Indian Space Research Organisation (Isro), speaking on the condition of anonymity, told IANS.

Launching of multiple satellites with a single rocket is nothing new for Isro and it has been doing that for several years. The challenge is however to launch several satellites at different orbits with one rocket and this is what Isro will be testing out after PSLV ejects out six Singaporean satellites on Wednesday.

The PSLV rocket is a four stage/engine rocket powered by solid and liquid fuel alternatively.

"Restarting a rocket engine soon after it is shut off is a critical technology that has to be mastered. Once a rocket engine is activated, then the heat generated is very high. The trick is to cool it down in the space and to restart it at a short gap," an industry expert told IANS.

"This is entirely different from switching on and off the communication satellite's engines in the space. The interval between two restarts of a communication satellite engine will be in days. But in the case of restarting a rocket engine, the time gap will be in hours," the expert added.

"By that time the rocket's engine has to be cooled down. This part of the experiment is very critical," he explained.

On Wednesday, Isro's PSLV rocket will blast off from the first launch pad at Sriharikota in Andhra Pradesh, around 80km from here, with the six Singaporean satellites. All the satellites will be put into orbit around 21 minutes into the flight at an altitude of 550km.

After that the rocket's fourth stage will be shut down.

"It will be coasting after that," an Isro official told IANS.

Around 46 minutes after the launch of the sixth satellite, the fourth stage will be restarted when it is in a lower altitude of 523.9 km.

The engine will be in operational for four seconds and would go up to an altitude of 524 km before the stage is cut-off.

Meanwhile Isro officials told the countdown for the December 16 evening launch of PSLV rocket is progressing smoothly.

On December 16, Isro will be flying the 'core alone' variant of the PSLV rocket. The rocket will not have the strap on boosters, its standard feature

The successful launch of the six Singaporean satellites will take Isro's total flights of foreign satellites to 57.

Out of the six satellites, the 400 kg earth observation satellite called TeLEOS-1 is the main passenger for the PSLV rocket and hence the mission is called TeLEOS mission by Isro.

TeLEOS-1 is Singapore's first commercial earth observation satellite designed and developed by ST Electronics.

The other five co-passenger satellites are VELOX-C1 (123 kg), VELOX-II (13 kg), Kent Ridge-1 (78 kg), Galassia (3.4 kg) and Athenoxat-1.

The December 16 mission will be the last rocket launch mission for Isro in 2015.

So far in 2015, Isro has launched 14 satellites (three Indian and 11 foreign) from its rocket port in Sriharikota. Thirteen satellites were launched with PSLV rocket and one communication satellite - GSAT-6-with geosynchronous satellite launch vehicle (GSLV).

Last month India also launched its communication satellite GSAT-15 using the Ariane rocket of the European space agency which takes the total number of satellite launches in 2015 to 21 (17 foreign, four Indian).
