The longest scanned document is 1,181 m (3,875 ft) achieved on a Trüper 3600 scanner by Böwe Bell + Howell (USA) at the HIMSS Annual Conference, Orlando, Florida, USA, on 25 February 2008. HIMSS = Healthcare Information and Management Systems Society The + in Bowe Bell + Howell is part of the name.
The living tree with the greatest circumference (girth) is that belonging to El Arbol del Tule in Oaxaca state, Mexico. This Montezuma cypress (Taxodium mucronatum) measured 42 m (137 ft) tall in 1998, with a girth of approximately 36 m (119 ft) and a diameter of 11.5 m (38 ft), at 1.5 m (5 ft) above the ground. The Tree of One Hundred Horses, a European chestnut (Castanea sativa) had a circumference of 57.9 m (190 ft) in 1780, but unfortunately, due to abuse over

The lightest Wi-Fi phone is the modu W, which weighs 62.7 g (2.2 oz). It is manufactured by modu Ltd. (Israel) and was measured at The Standards Institution of Israel (SII) in Tel Aviv, Israel, on 21 September 2010. An example of the phone was submitted as evidence. It’s the same chassis as the modu-T (Lightest touch screen mobile (cell) phone, ATT ID 118869) but trades in access to 3G and GPRS in exchange for Wi-Fi. This means that it’s only capable of making phone

The lightest touchscreen mobile phone is the sWaP Nova, which weighs 40.3 g (1.42 oz) and was achieved at the Gadget Show Live in Birmingham, UK on 12 April 2011. It is manufactured by Dyal Trading Ltd. (UK). The phone measures (L)68.5 x (W)38 x (D)16.2 mm (2.7 x 1.5 x 0.64 in).
The world’s lightest tent is the Laser Photon Elite, by Terra Nova Equipment (UK), a one-man tent that has a mass of 587.9 g (20.7 oz), and was weighed in Derbyshire, UK, on 29 September 2010. The mass of the tent includes the inner sheet, flysheet, aluminium pole, guylines, 2 carbon fibre support poles, 2 elastics, 12 pegs, peg bag, pole bag, outer bag and even 1 extra guy line and 6 extra flysheet elastics.
The entire hull of the Advanced Composite Armoured Vehicle Platform (ACAVP) tank is manufactured from E-glass epoxy, a plastic/fibre-glass composite material strong enough to protect its crew from rifle and artillery fire but making it 10% lighter than an equivalent in-service metallic-hulled tank. The prototype vehicle was developed by the British Defence Evaluation and Research Agency (DERA) and was first demonstrated in March 2000. It weighs just 24 tonnes (52,910 lb). To provide protection from other tanks additional metal armour is mounted on the outside

The lightest commercially available spectacles frame weighs 1.01 grams (0.04 oz) and is produced by Spectral Optics and Mr Nestor Clemente Grimaldi (both Mexico). It was presented and weighed in Mexico City, Mexico, on 20 May 2010. The frame consists of three separate pieces that only form a pair of spectacles together with some glasses. The weight was the pieces of the frame plus nose pads. The weight without nose pads was 0.77 grams (0.03 oz). The weight was the average of weighing three different

The lightest remote-controlled model helicopter is the PicooZ MX-1 by Silverlit Toys Manufactory Ltd. (Hong Kong) it weighs 8 g (0.28 oz) and was manufactured in Causeway Bay, Hong Kong. The MX-1 is a smaller version of the previous record holder, the PicooZ. The remote transmitter is also the helicopter’s ‘hanger’ where the helicopter recharges and can be stored when not flying.
Scientists at Cornell University (USA) have used a technique involving tiny oscillating cantilevers to physically detect a mass of just 6.3 attograms. The work was carried out by Professor Harold Craighead and Rob Ilic (both USA) and published in April 2004. An attogram is a billionth of a billionth of a gram.
The lightest known particles in the universe are neutrinos which have a maximum mass of 0.0000000000000000000000000000000000018 kg. Neutrinos are come in three varieties – electron, muon and tau neutrinos. The mass is an average of the three types. Neutrinos are created by radioactive decay and nuclear fusion (the process that powers the sun). The mass of the particles was successfully calculated by scientists at Cambridge University and announced at the Royal Astronomical Society’s annual conference in Bristol on 10 April 2002. These particles interact only
