7 Amazing Holes

7 Amazing Holes

Looking at photos like these scares and fascinates me in equal doses. the sheer scale of these holes reminds you of just how tiny you are.

Kimberley big hole - South Africa

Apparently the largest ever hand-dug excavation in the world, this 1097 metre deep mine yielded over 3 tonnes of diamonds before being closed in 1914. the amount of earth removed by workers is estimated to total 22.5 million tonnes

Glory hole - Monticello Dam

A glory hole is used when a dam is at full capacity and water needs to be drained from the resevoir

This is the glory hole belonging to monticello dam in california and it ïs the largest in the world, its size enabling it to consume 14400 cubic feet of water every second.

The hole can be seen at the top left of the photo above. if you were to jump in for some reason your slightly damp body would shoot out near the bottom of the dam .

Bingham Canyon Mine, Utah

This is supposedly the largest man-made excavation on earth. extraction began in 1863 and still continues today, the pit increasing in size constantly. in its current state the hole is 3/4 mile deep and 2.5 miles wide.

Great Blue Hole, Belize

Situated 60 miles off the mainland of belize is this incredible ��geographical phenomenon ïs known as a blue hole. there are numerous blue holes around the world but none as stunning as this one.

At surface level the near perfectly circular hole is 1/4 mile wide, the depth in the middle reaching 145 metres. obviously the hole is a huge hit with divers.

Socotra Island - Seeing is Believing

Socotra Island - Seeing is Believing

Socotra Island (derived from Sanskrit meaning "Island of Bliss") blows away any notion about what is considered "normal" for a landscape on Earth. It is like being on a different planet... These pictures and information are excellent viewing and reading.

Imagine waking up on the Socotra Island and taking a good look around you. After a yelp of disbelief, you'd be inclined to think you were transported to another planet - or traveled to another era of Earth's history. The second would be closer to the truth for this island, which is part of a group of four islands, has been geographically isolated from mainland Africa for the last 6 or 7 million years. Like the Galapagos Islands, this island is teeming with 700 extremely rare species of flora and fauna, a full 1/3 of which are endemic, i.e. found nowhere else on Earth.

The climate is harsh, hot, and dry, and yet - the most amazing plant life thrives there. Situated in the Indian Ocean 250 km from Somalia and 340 km from Yemen, the wide sandy beaches rise to limestone plateaus full of caves (some 7 km in length) and mountains up to 1,525 metres high.

The name Socotra is derived from a Sanskrit name, meaning "The Island of Bliss"... Is it the beaches? The isolation and quiet? Or the strange and crazy botanical allure? Alien-looking plants: H.P. Lovecraft's secret inspiration? Was the famous Chtulhu myths creator aware of these forbidding mountains with their hauntingly weird flora (think of plant mutations from his "The Colour Out of Space")? We’re almost tempted to call Socotra the other "Mountains of Madness" - the trees and plants of this island were preserved through the long geological isolation, some varieties being 20 million years old... We begin with the dracena cinnibaris or Dragon's Blood Tree, the source of valuable resin for varnishes, dyes, and "cure-all" medicine; also (predictably) used in medieval ritual magic and alchemy.

The branches spread out into the sky and from below appear to hover over the landscape like so many flying saucers... and from above, they have a distinct mushroom look:

There is also the Desert Rose (adenium obesium) which looks like nothing so much as a blooming elephant leg:

This island is a birder's paradise as well, with 140 different species of birds, 10 of which are not found anywhere else in the world. A unique Socotra warbler, sunbird, starling, bunting, sparrow, and cisticola are among the ones found here. There are also Socotra Cormorants:

Socotra is one of those "lost world" islands (separated from the world six million years ago) where intrepid travellers - particularly those seeking exotic nature and wildlife in a remote tropical setting - can go days on end without rubbing shoulders with that less-than-endangered species: tourists.

Timeline of Wireless Technology

What is wireless communication? In layman's language it can be described as using technology to transfer information over a distance without using any wires. Wireless communication is not new and has been in use for well over 125 years now. Through this article we trace the origin of this technology and its evolution to its present form. Here is the timeline of wireless technology.

1887

The principle of wireless communication was presented by German physicist Heinrich Hertz in the year 1887. Hertz demonstrated how electromagnetic waves could be transmitted across free space. This was an expansion of the theory of electromagnetic theory of light put forth earlier by James Maxwell and Michael Faraday. Though Hertz managed to demonstrate it, he never tried to take it any further, even remarking that it would be of no significance.

1893

Nikola Tesla transmits radio waves in St. Louis, Missouri.

1897

Guglielmo Marconi is awarded the British Patent for 'Improvements in transmitting electrical impulses and signals and in apparatus there-for'. What this effectively means is that he was granted the rights to the Radio.

1898

Nikola Tesla demonstrates a remote control boat. It would be amusing to know that people watching this demonstration thought Tesla was controlling the boat using his mind, as nobody seemed to have any information about radio waves at that time.

1906

Amplitide Modulation (AM) is used by Reginald Fessenden to broadcast his voice over the North Atlantic. This mode of radio transmission is the same as Shortwave and Medium wave in use today.

1915

First transatlantic transmission takes place. AT&T achieves this radio transmission from Arlington, Virginia to Paris using the Eiffel Tower to hold the receiving antenna.

1919

Radio Corporation of America (RCA) is incorporated by General Electric (GE) on Oct. 17 specifically to acquire the assets of the wireless radio company American Marconi from British Marconi.

1921

Shortwave (SW) radio is developed. It is called Shortwave because the wavelength of light is shorter than visible light due to the higher frequency. Shortwave Radio (also known as High Frequency or HF radio) has a frequency of 2.310 Megahertz to 25.820 Megahertz. The benefit of Shortwave radio is that the waves can bounce off the ionosphere (the layer of atmosphere consisting of ions or charged particles), enabling transmission to the other side of the world without actually having a direct line of sight.

1931

Frequency Modulation or FM is developed by Edwin H. Armstrong. FM transmission is less prone to noise associated with AM transmission and therefore results in a clearer broadcast. Also, it is possible to transmit stereo signals, making it suitable for musical radio broadcasts.

1982

The GSM (Groupe Special Mobile) group is formed and decides on a digital system for its cellular systems

1983

After decades of stagnation in wireless communication technology, 802.3 standard is created by IEEE and additions to its specifications are made regularly.

1987

GSM Technical details are worked out in this year. A narrowband time division multiple access (TDMA) system is also planned.

1990

L-band radio is demonstrated (digital radio). The Global Positioning System (GPS) operates in the L-Band. Also, first GSM specifications are released.

1991

The first GSM call is made in Finland (March) on the Radiolinja network, which got its GSM license in 1990. This is the precursor to Wi-Fi developed by NCR Corporation in the Netherlands with speeds up to 1-2 Mb/s.

1992

First GSM network outside Europe network is launched in Australia on April 27 providing service to 53% of the Australian population.

1997

IEEE 802.11 (also known as Wi-Fi) standard is created. This original 802.11 specification has a maximum bandwidth of 2 Mb/s.

1998

The Bluetooth Special Interest Group (SIG) was formed in September of 1998 by Ericsson, Intel, IBM, Toshiba and Nokia. The formal announcement of the SIG takes place next year on May 20, 1999.

1999

IEEE 802.11b is added to the 802.11 standard. Transmission speeds up to 11 Mb/s are possible. Bluetooth 1.0 (IEEE 802.15.1) specification is released. In this, all hardware identifies itself in the handshake process and renders anonymous data reception and transmission impossible. EV-DO (Evolution Data Optimized) is developed by Qualcomm.

2000

The first consumer Bluetooth product - a wireless headset and phone adapter for mobile phones is released by Ericsson.

2001

The first 3G network is commercially launched in September by NTT DoCoMo, Japan. In December, IEEE 802.16 standard, also known as WiMAX, is created.

2002

The first UMTS network is launched allowing high-speed applications such as mobile TV and video calling.

2003

EDGE is deployed by AT&T on Singular network in the USA. IEEE 802.11g is added to the 802.11 standard, allowing transmission speeds up to 54 Mb/s. Bluetooth specification 1.2 is released. This new specification includes Adaptive Frequency-hopping (AFH), which reduces RF interference.

2004

Newest version of IEEE 802.16 is added and it completely changes the WiMAX standard. This has a new scheduling algorithm, which makes WiMAX much more scalable than Wi-Fi. Instead of the random way in which subscribers compete in Wi-Fi, they compete once for a time to call when they connect to the network, thereby reducing collisions when transmission occurs at specified times. Bluetooth specification 2.0 is released. This new specification is not only backward compatible but also introduces Enhanced Data Rate (EDR), which allows transmission of data up to 3 MB/s.

2009

802.11n - the latest in Wi-Fi standards will be formally approved in November 2009 (although devices sporting this standard are already available, they are not necessarily conformant with the final specifications).

10 Dangerous Exotic Pets

10 Dangerous Exotic Pets

10. Turtles

A turtle may seem harmless enough, but did you know that they actually carry salmonella? It seems that the main concern is the baby turtles. It is not that the little guys have more cases of salmonella, it’s that the smaller they are the more attracted little kids are to them. And we all know how little kids can be; they will stick just about anything in their mouth – including their fingers after touching the turtles and the turtles themselves.

9. Constrictors

This is pretty much an obvious one. Sure that red tailed boa at the pet store seems harmless and kind of cute. But they grow quite rapidly; can get up to several feet in length, and speaking from a neighborhood experience, they have been known to escape. Lets just say if you feed them rabbits, they would have no problem with getting themselves around a dog or a cat even. One of the main concerns with owning constrictors is that once they start to get large, some people actually just let them go and return them to the wild.

8. Scorpions

Did you know that there is a guy that as a performance and a world record chaser, he actually puts live Scorpions in his mouth? That’s not one of the best ideas you would have heard of. These little guys can pack quite a punch with their venomous sting!

7. Camels

Camels are known to be pretty temperamental guys. According to a report on Fox News when a local TV news crew was out filming exotic animal farms, an 1800 lb camel named Polo must have decided that they were not shooting his best side. When Polo became agitated he attacked his owner, kicking her and sitting on her. Ouch. Oh, and if you didn’t know, camels like to spit too. And it’s pretty gross.

6. Ostriches

Sure they seem cute and awkward looking. They hide their heads in the ground right. But apparently these guys will also chase you and they run pretty darn fast. Getting in the middle of an ostrich stampede just doesn’t sound like my idea of a really good time.

5. Chimps and Monkeys

They are adorable. The human resemblance is amazing. They are also known to bite and attack humans and animals alike. It was once seen the damage that a monkey caused when it attacked a dog in India and let’s just say those puncture wounds weren’t pretty. The dog also lost an ear and an eye in the process. Sometimes cute is pretty deceptive.

4. Venomous Snakes

They are snakes. They are poisonous. They bite. None of this is a good combination. In Cincinnati a man was bitten by his rhinoceros viper snake, which is one of the world’s deadliest snakes. He did receive anti-venom and survived. But who really wants to take that risk?

3. Crocodiles and Alligators

Often people get crocs and alligators when they are little and cute and look like happy little lizards. Have you seen the jaws on those things? They didn’t make an entire TV show around hunting them out if there wasn’t some sort of risk and danger there. So keeping one in a kiddie pool in the back yard may not be the best idea. Just ask anyone who has lived in Florida and found one under their car.

2. Big Cats

Again it’s these cute ones that you have to worry about. When these guys are babies, who could resist? But no matter how young they are or how well trained they are, they can turn on you in a second. They feed them raw steak for goodness sake, shouldn’t that be a sign?

1. Kinkajou

A kinkajou, also known as a sugar bear, looks like a cross between a squirrel, a hamster, and a chinchilla. They are pretty darn cute. But again it’s the cute ones. Paris Hilton has a pet kinkajou named Baby Luv. In 2005 she took it shopping with her and was attacked by the thing and it clawed up her face. The brilliance of this is that again in 2006 Baby Luv sent Hilton to the emergency room after she was bitten by that cute Baby Luv on the arm. And that is why this guy is number one on my list of dangerous pets…. Come on, cute rainforest animal that attacks Paris Hilton numerous times. You got to put that one at the top of the list just because.

Most countries have laws against them. In most places around the globe it is illegal to capture, breed, or sell them. Yet world wide there is a fascination with owning wild, bizarre, exotic, and most of the time dangerous pets.

The United With Animal Protection Institute issued a report of incidents involving captive held animals, which provided an interesting background report to base the list upon. There are also stories like this in papers around the world concerning the practice of keeping dangerous and exotic pets.
