The Corsi block tapping task originated in the early 1970s [2] as a set of 9 identical wooden blocks positioned on a board. The subject was required to point at the blocks in the order they were presented, or "tapped". It was based on the digit span task, but instead of the verbal form of the Digit Span, it required the use of visuo-spatial ...
The first nine blocks in the solution to the single-wide block-stacking problem with the overhangs indicated. In statics, the block-stacking problem (sometimes known as The Leaning Tower of Lire (Johnson 1955), also the book-stacking problem, or a number of other similar terms) is a puzzle concerning the stacking of blocks at the edge of a table.
Wood physics encompasses critical research areas including: a) examining wood behaviour in relation to moisture, which involves fundamental aspects of moisture absorption, swelling, and shrinkage, b) investigating the impact of temperature on wood properties, encompassing heat conduction and heat storage, and c) assessing the mechanical ...
Nicolson pavement, alternatively spelled "Nicholson" and denominated wooden block pavement and wood block pavement, is a road surface material consisting of wooden blocks. Samuel Nicolson invented it in the mid-19th century. [1] Wooden block pavement has since become unfavored because of its poor surface quality and high cost of maintenance.
The Forest Products Laboratory (FPL) is the national research laboratory of the United States Forest Service, which is part of USDA.Since its opening in 1910, the FPL has provided scientific research on wood, wood products and their commercial uses in partnership with academia, industry, tribal, state, local and other government agencies.

The Atwood machine (or Atwood's machine) was invented in 1784 by the English mathematician George Atwood as a laboratory experiment to verify the mechanical laws of motion with constant acceleration. Atwood's machine is a common classroom demonstration used to illustrate principles of classical mechanics .
Robins experimented with musket balls of around one ounce in mass (28 g), while other contemporaries used his methods with cannon shot of one to three pounds (0.5 to 1.4 kg). [6] Robins' original work used a heavy iron pendulum, faced with wood, to catch the bullet. Modern reproductions, used as demonstrations in physics classes, generally use ...
Wood's metal. Uses include making custom-shaped apertures and blocks (for example, electron-beam cutouts and lung blocks) for medical radiation treatment, and making casts of keys that are hard to otherwise duplicate. [5] [6] Like other fusible alloys, e.g. Rose's metal, Wood's metal can be used as a heat-transfer medium in hot baths. Hot baths ...
