The smallest operational telephone was created by Jan Piotr Krutewicz, Munster, USA on 16 September 1996. It measured just 47.5mm x 10mm x 21mm 1.8in x 0.3in x 0.8 in.

Zeng Jinlian (China) (b. 26 June 1964) of Yujiang village in the Bright Moon Commune, Hunan Province, measured 2.48 m (8 ft 1.75 in) when she died on 13 February 1982. This figure represented her height with assumed normal spinal curvature because she suffered from severe scoliosis (curvature of the spine) and could not stand up straight. She began to grow abnormally from the age of four months and stood 1.56 m (5 ft 1.5 in) before her fourth birthday and 2.17 m (7 ft Continue reading →

LG Korea has created a fully hi-def (1,920 x 1,080 pixel) liquid-crystal display panel that is a mere 2.6 mm (0.10 in) thick ­ thinner than a UK £1 coin. The 106-cm (42-in) screen uses an ultraslim LED blacklighting system, and the entire unit weighs just 4.2 kg (9 lb 4 oz).

Samsung’s (South Korea) Ultra Edition 8.4 Z370 is the world’s thinnest 3G mobile phone, featuring a 2-mega-pixel camera mounted in a body just 8.4 mm (0.3 in) thick and just 71 g.

In October 2004 British and Russian scientists announced their discovery of the nanofabric graphene. With a thickness of just one single atom of carbon, graphene is similar to carbon nanotubes and buckyball carbon 60 molecules, but can exist as a single sheet of theoretically an infinite size. In March 2007 scientists announced the development of transistors made from this remarkable material.

Casio’s 12.1-megapixel Exilim EX-H10 digital camera is, at 24.3 mm (just under 1 in) thick, the slimmest digital camera with a x10 optical telephoto zoom. At just 164 g (5.78 oz), it is also among the lightest. It can take 100 pictures a day for 10 days without needing to be charged.

The thickest armour ever carried was in HMS Inflexible (completed 1881), measuring 60 cm (24 in) backed by teak up to a maximum thickness of 107 cm (42 in).

The greatest recorded thickness of ice is 4,780 m (15,682 ft; 2.97 miles), as measured by radio echo soundings from a US Antarctic research aircraft at 69ø56’17. In addition, on 4 January 1975, a team of seismologists measured the depth of ice in Wilkes Land, in eastern Antarctica, to be 4,776 m (15,669 ft; 2.96 miles) deep.

Flipping a Michelin Radial Steel Cord X26.5R25 (XHA) tyre weighing 420 kg (925.9 lb), Israel Garrido Sanguinetti (Spain), completed a 20-m (65.6-ft) course (10 m (32.8 ft) there and back) in a time of 56.3 sec at the studios of El Show de los Récords, Madrid, Spain on 11 December 2001.
