• Sir Jagdish Chandra Bose invented the Crescograph, an electrical instrument that could measure the growth of a plant.
• It was capable of magnifying the motion of plant tissues to about 10,000 times of their actual size and, in doing so, found many similarities between plants and other living organisms.

• The Hubble Deep Field, sometimes called the HDF, is an image of a small part of the night sky in the constellation Ursa Major that was taken by the Hubble Space Telescope in 1995.
• It is important because it shows some of the farthest away galaxies ever seen, over 3000 in total.
• It has imaged some of the most distant galaxies ever observed, allowing the telescope to look back in time to when the universe was in its infancy.

• EcoBot III is a lightweight self-sustaining robot that runs off human waste, using it to produce electricity necessary for performing its cleaning task.
• The main objective of the project was to create a self-sufficient machine with an onboard fluid circulation that would collect energy from its environment and get rid of its own waste.
• The robot is only about 6 kg and consists of the ingestion, artificial digestion and solid waste excretion mechanism.

• The International Astronomical Union is a worldwide society of professional astronomers and is considered the authority for assigning names to celestial objects, whether they are planets or moons or other types of worlds, as well as surface features on them.
• Its mission is to promote and safeguard the science of astronomy in all its aspects, including research, communication, education and development, through international cooperation.

• The Internet's first search engine, the Archie system, was created in 1989 by the student at the McGill University in Montreal, Canada, Alan Emtage.
• Archie is considered the original search engine and a lot of the techniques that Emtage and other people that worked with him on Archie came up with are basically the same techniques that Google, Yahoo! and all the other search engines use.
• Archie helped users find files in the directories of public hosts that they might never have otherwise discovered.

• Juno is the first mission designed by NASA to see beneath Jupiter’s clouds.
• Juno's primary goal is to reveal the story of Jupiter's formation and evolution. It will also observe Jupiter's gravity and magnetic fields, atmospheric dynamics and composition.
• It will have a mission life of 20 months from July 2016 to Feb 2018. In its mission life, the spacecraft will circle the Jupiter 37 times before finally making a death plunge in 2018 in order to avoid accidentally crashing onto one of the planet’s moons.

• Hubble is a space telescope that was launched in 1990 by NASA in collaboration with European Space Agency. It is named after the astronomer Edwin Hubble and is still in operation.
• It is located in low Earth orbit outside the distortion of Earth’s atmosphere that allows it to take extremely high-resolution images.
• With the completion of the last servicing mission in 2009, Hubble remains in good health and is pegged to continue operations well past the year 2020.

• Robonaut is a NASA robot. Engineers designed Robonaut to be humanoid, which means it is built to look like a person. This makes it easier for Robonaut to do the same jobs as a person.
• Robonaut could help with anything from working on the International Space Station to exploring other worlds.

• The Fermi Gamma-Ray Telescope is a space observatory designed to study the universe in highly energetic frequencies known as gamma-rays.
• It includes participation from NASA, the U.S. Department of Energy, and several partners both in the United States and internationally. The mission was launched in 2008

• Apple acquired Lattice for 200 million dollars in 2017.
