Many of these missions took place along or over communist controlled territory, with 90th SRW aircraft first flying to Thule AB, Greenland then probing deep into the heart of the Soviet Union, taking a photographic and radar recording of the route attacking SAC bombers would follow to reach their targets.

Many early Crookes tubes undoubtedly generated X-rays, because early researchers such as Ivan Pulyui had noticed that they could make foggy marks on nearby unexposed photographic plates.

Many of Muybridge's photographic sessions using the zoopraxiscope had nude anonymous models, both female and male, and indeed even Walt Whitman and George Bernard Shaw posed nude for a session.

Many photographic lenses produce a superior image in the center of the frame than around the edges.

Many industries, notably textiles, firearms, clocks and watches, buttons, horse-drawn vehicles, railroad cars and locomotives, sewing machines, and bicycles, saw expeditious improvement in materials handling, machining, and assembly during the 19th century, although modern concepts such as industrial engineering and logistics had not yet been named.

Many ancient cultures, including the ancient Egyptians and ancient Greeks, used specially selected mold and plant materials and extracts to treat infections.

Many of these materials were initially published in Church periodicals in the early days of church.

Many of the successful programs were transitioned to the Services, such as the foundation technologies in automatic target recognition, space based sensing, propulsion, and materials that were transferred to the Strategic Defense Initiative Organization ( SDIO ), later known as the Ballistic Missile Defense Organization ( BMDO ), now titled the Missile Defense Agency ( MDA ).

Many very hydrophobic materials found in nature rely on Cassie's law and are biphasic on the submicrometer level with one component air.

Many of these industries consume large quantities of energy and require factories and machinery to convert the raw materials into goods and products.

Many paint makers now offer faux-maroger's media or faux-megilps, generally made by substituting different materials, such as lime, for genuine lead, or ( as in the case of Gamblin's Neo-Megilp ) by creating a similar product out of specially thickened alkyd medium.

Many modern stretchy garments, even as they rely on elastic synthetic materials for some stretch, also achieve at least some of their stretch through knitted patterns.

Many materials have been employed in knife handles.

Many institutions make a distinction between a circulating or lending library, where materials are expected and intended to be loaned to patrons, institutions, or other libraries, and a reference library where material is not lent out.

Many pseudo-leather materials have been developed, allowing those who wish to wear leather-like garments to do so without actually wearing leather.

Many materials can be substituted for mica in numerous electrical, electronic, and insulation uses.

Many other materials also serve to make decorated nutcrackers, such as porcelain, silver, and brass ; the museum displays samples.

Many photographers continue to produce some monochrome images, often because of the established archival permanence of well processed silver halide based materials.

Many materials, both natural and synthetic, exhibit piezoelectricity:

Many other cuprate superconductors have since been discovered, and the theory of superconductivity in these materials is one of the major outstanding challenges of theoretical condensed matter physics.

Many of these newer materials, such as rubber and plastics, have made shoes less biodegradable.

Many materials are used, but nickel-plated brass is popular for the highest-quality slides, which are shaped to fit the hand and as a result have a cross-section not unlike a railroad track.

Many toxic materials are used in the fabrication process.

Many efforts were made to develop a solid-state amplifier, but these were unsuccessful because of limited theoretical understanding of semiconductor materials.
