  • Up in the air: A week in aerospace

    Andrew WadeSenior reporterAs our readers will know, The Engineer is a very broad church that tries to cover all branches of the vast engineering expanse, from automotive and energy, to chemical and marine. Nonetheless, every once in a while we have a week where one sector tends to dominate. For me this week that sector was aerospace, and there were no complaints coming from my direction.
    Aerospace is perhaps engineering’s sexiest façade, the manifestation of humanity’s seemin

  • Surface absorbs 98% of photons

    Australian researchers have increased photon absorption in a semiconductor to almost 99%, according to the University of Sydney. The absorber is a sub-wavelength thin-film semiconductor, and no complex nano-structures, meta-materials, exotic materials or difficult-to-create metal-non-metal combinations have been used. When light falls on a thin film etched with narrow grooves, light is directed sideways and ...

  • May 1915: The Gretna Rail Disaster

    This month The Engineer looks back to a very dark day in British history, and the worst rail disaster the UK has ever suffered.
    On 22 May 1915, five separate trains were involved in a devastating crash at the Quintinshill signal box near Gretna Green in Dumfriesshire, Scotland.
    Gretna Green was the UK’s worst ever rail disasterThe collisions and subsequent fire resulted in the loss of at least 226 lives, although a definitive number of victims has never been established.
