A nanometer (nm) is a unit of length in the metric system, equal to one billionth of a meter (10^-9 meters). It is commonly used to measure things on the molecular and atomic scales, such as the wavelengths of light, the dimensions of biological structures, and the sizes of semiconductor components in electronics.

Definition and Scale

• Size Comparison:

  • 1 nanometer = 0.000000001 meters (10^-9 meters)

  • For context, a single strand of human DNA is about 2.5 nanometers in diameter.

  • A typical human hair is about 80,000 to 100,000 nanometers wide.

  • A red blood cell is approximately 7,000 nanometers in diameter.

Applications

1. Nanotechnology:

   • Nanomaterials: Materials engineered at the nanometer scale often exhibit unique properties, such as increased strength, lighter weight, and higher chemical reactivity. Examples include carbon nanotubes and quantum dots.

   • Nanodevices: The development of nanoscale devices, such as nanosensors and nanorobots, has potential applications in medicine, electronics, and environmental monitoring.

2. Semiconductor Industry:

   • Transistors: Modern microprocessors use transistors with dimensions measured in nanometers. The smaller the transistor, the more can fit on a chip, increasing computing power and efficiency.

   • Manufacturing Processes: Semiconductor fabrication processes are often described in terms of nanometers, such as the 7nm, 5nm, or even 3nm process nodes.

3. Biology and Medicine:

   • Biological Structures: Many biological structures, such as proteins, viruses, and cell membranes, are best described in nanometers. This scale is crucial for understanding cellular processes and developing medical treatments.

   • Drug Delivery: Nanoparticles can be used for targeted drug delivery, improving the efficacy and reducing the side effects of treatments.

4. Optics and Photonics:

   • Wavelengths of Light: Visible light has wavelengths in the range of approximately 400 to 700 nanometers. Understanding and manipulating light at this scale is essential for developing optical devices such as lasers and photonic circuits.

   • Nano-Optics: The field of nano-optics involves studying and controlling light at the nanometer scale, with applications in imaging, sensing, and information processing.

5. Materials Science:

   • Surface Properties: Nanotechnology allows for the modification of surface properties of materials, leading to innovations like self-cleaning surfaces, enhanced catalysts, and improved coatings.

Measurement and Tools

• Electron Microscopy: Scanning electron microscopes (SEMs) and transmission electron microscopes (TEMs) are capable of imaging structures at the nanometer scale.

• Atomic Force Microscopy (AFM): AFM is a type of scanning probe microscopy with very high resolution, able to measure features at the nanometer level by "feeling" the surface with a mechanical probe.

Challenges

• Precision and Control: Working at the nanometer scale requires extremely precise control over the fabrication and manipulation of materials, often pushing the limits of current technology.

• Cost and Scalability: The cost of developing and manufacturing nanoscale materials and devices can be high, and scaling up production to industrial levels presents additional challenges.

It was Faraday’s discovery in 1821 of the principle of electro-magnetic rotation that would later be the key to developing the electric motor. And it was Joseph Swan who actually invented the first incandescent lightbulb; however, his lightbulb burned out quickly

Most students of Biology are aware of the Watson & Crick Double Helix Model of DNA. Fewer take note of the research by Rosalind Franklin that pre-dated the DNA model of 1962. Working in the laboratory of Maurice Wilkins, Franklin exposed a crystallized form of DNA to X-Rays to reveal clues about the structure of the molecule.

Franklin discovered that some of the rays are deflected by the atoms in the crystal, forming a diffraction pattern. Watson and Crick then employed this imaging, along with Edwin Chargaff’s findings about A, C, T, G nucleotides - to come up with their model.

Watson and Crick, along with Chargaff and Wilkins received the Nobel Prize in Medicine in 1962. Unfortunately, Franklin had by then passed away - and prizes were not awarded posthumously.

A geodesic dome is a spherical or partial-spherical structure composed of a network of triangles. This triangular network distributes stress evenly across the structure, making it exceptionally strong relative to its weight.

The concept of geodesic structures can be traced back to earlier mathematical work by engineers and mathematicians like Walther Bauersfeld, who designed a geodesic dome for the Zeiss planetarium in 1922. However, it was popularized by Buckminster Fuller - who improved the design and made it suitable for commercial production.

While the theorem was known to Babylonian mathematicians before Pythagoras, he and his followers are credited with providing the first known proof.
