Beatriz Barbuy is a Brazilian astronomer known for her research in astrophysics and stellar populations. She has made significant contributions to the understanding of the formation and evolution of stars, particularly in relation to chemical abundance patterns in different galaxies. Barbuy is also involved in promoting science education and outreach in Brazil. Her work often emphasizes the importance of collaboration in the international scientific community.

Brigitta Sipőcz is known for her involvement in the field of art, particularly as a Hungarian artist and designer. Her work often includes elements of craftsmanship and creativity, exploring various mediums.

As of my last update in October 2023, there is no widely recognized information or notable figure named Maritza Lara-López. It is possible that she may be a private individual or someone who has gained prominence more recently.

As of my last knowledge update in October 2021, there isn't any widely recognized figure, event, or concept known as "Elsa Recillas." It's possible that she is a private individual or a local personality who gained attention after that date, or it could be a name from a specific context such as literature, social media, or a niche field.

As of my last knowledge update in October 2023, "Gloria Dubner" does not appear to refer to a widely recognized person, concept, or term. It’s possible that it may refer to a private individual, a lesser-known figure, or a topic that emerged after my last update.

Jacqueline Hewitt is an astrophysicist known for her work in the field of astrophysics, particularly in areas related to gravitational waves and the structure of the universe. She has made significant contributions to our understanding of cosmology and the behavior of stars in the universe. Hewitt has also been involved in various educational and outreach activities aimed at promoting science and encouraging young people to pursue careers in STEM (science, technology, engineering, and mathematics).

Julie Vinter Hansen is not a widely recognized public figure or term, as of my last knowledge update in October 2023. It's possible that she could be a private individual, an emerging personality in a specific field, or a fictional character.

Loretta Gregorini does not appear to be a widely recognized public figure, concept, or term as of my last knowledge update in October 2023. It is possible that she is a private individual, or perhaps a lesser-known person in a specific context.

Louise Gray Young is not a widely recognized figure or concept up until my last knowledge update, so there may be various individuals or contexts in which this name appears.

Discovered in 1988, the first high-temperature superconductor which did not contain a rare-earth element.

Many devborads require a 5V power supply.

This is common on wall transformers and USB, but not in batteries.

For battery power you need a transformer.

Many/most microcontroller boards have analog-to-digital converters built into them, it is very convenient. E.g. it is the case for the Raspberry Pi Pico.

Small microscopic visible particles move randomly around in water.

If water were continuous, this shouldn't happen. Therefore this serves as one important evidence of atomic theory.

The amount it moves also quantitatively matches with the expected properties of water and the floating particles, was was settled in 1905 by Einstein at: investigations on the theory of the Brownian movement by Einstein (1905).

This suggestion that Brownian motion comes from the movement of atoms had been made much before Einstein however, and passed tortuous discussions. Subtle is the Lord by Abraham Pais (1982) page 93 explains it well. There had already been infinite discussion on possible causes of those movements besides atomic theory, and many ideas were rejected as incompatible with observations:The first suggestions of atomic theory were from the 1860s.

Tiny uniform plastic beads called "microbeads" are the preferred 2019 modern method of doing this: en.wikipedia.org/wiki/Microbead

Original well known observation in 1827 by Brown, with further experiments and interpretation in 1908 by Jean Baptiste Perrin. Possible precursor observation in 1785 by Jan Ingenhousz, not sure why he wasn't credited better.
