How Science Aids Beauty by Solving Mirror Mysteries
A science guided look at mirrors explains how image size changes with distance and mirror type. It covers plane, concave, and convex mirrors, and shows why distant objects sometimes appear enlarged or diminished.

Radio Signal Fading Linked to Standards Lab Findings
The piece explains fluctuating radio reception tied to fading and cites the U S Bureau of Standards and 23 cooperating laboratories, including telephone and radio firms and universities. It notes no cure but offers cause and effect insights for scientists and curious readers.

Inventors Propose Metal Pontoons for Hydroplanes and Aerial Antennas
The Navy eyes duralumin for hollow pontoon floats in hydroplanes as light as aluminum yet as strong as steel. French inventor Alphonse Dayde debuts a pedal driven water craft, while Arthur Nilson of Brooklyn showcases a radio antenna balloon system. Also noted are a fold out sink design by Walter Grover and a study on radio wave fading across a wide Atlantic to Massachusetts routes.

Marriages to Trees in Indian Tribes and Odd Customs
A descriptive piece notes tribal practices in India where men or women wed sacred trees or inanimate objects to avert misfortune from death or prior marriages. It cites Bardoli near Ahmedabad where a Brahmin girl married a pipal tree, followed by a caste dinner, and mentions other ritual substitutes for wedlock. It also references broadcasting power fading in radio signals and its unusual periodicity after sunset.

Cattails Proposed as New Food Source and Flour
The cattail plant is explored as a potential food supply. Native peoples used roots as flour and pulp for bread and puddings, while Maori use pollen for bread. Government analysis shows protein similar to rice and corn flours, fat lower than wheat, and experiments show 10 to 20 percent cattail flour could substitute wheat in baking. Biscuits with up to half cattail flour were palatable.
Why Victims of Amok Become Murderers
A Batavia Medical School study on Malay amok argues it is a mental distress syndrome triggered by infectious illness such as malaria or influenza. It describes sudden, panicked violence ending in amnesia, with amok linked to emotivity and suggestibility in Malays, not epilepsy.

Tests on fabrics show heat and wind resistance depend on weave density
United States Bureau of Standards reports that fabric heat retention and wind protection hinge on weave closeness and density. Air permeability and moisture transmission measured with a gas cylinder and moisture beakers confirm that moderate density fabrics balance heat retention and wind resistance, while heavy fabrics block wind but lose heat differently. A separate item notes John S. Vanek of Oklahoma City introducing a short barreled penholder for the second finger to reduce fatigue.
