Galileo's demonstration that falling objects must fall at the same rate regardless of their masses was a significant step forward in the history of modern science. This is widely thought [ 12 ] to have been a straightforward physical demonstration, involving climbing up the Leaning Tower of Pisa and dropping two heavy weights off it, whereas in ...
Einstein later refined his thought experiment to consider a man inside a large enclosed chest or elevator falling freely in space. While in free fall, the man would consider himself weightless, and any loose objects that he emptied from his pockets would float alongside him. Then Einstein imagined a rope attached to the roof of the chamber.
This article focuses on the LOM data model rather than issues relating to XML or other bindings. IMS Global Learning Consortium is an international consortium that contributed to the drafting of the IEEE Learning Object Metadata (together with the ARIADNE Foundation) and endorsed early drafts of the data model as part of the IMS Learning ...
And there is the risk that we come to see others as objects to be accessed--and only for the parts we find useful, comforting, or amusing". [57] Furthermore, social network sites can create insincere friendships, Turkle also noted, "They nurture friendships on social-networking sites and then wonder if they are among friends.

[1] [2] Data may represent abstract ideas or concrete measurements. [3] Data are commonly used in scientific research, economics, and virtually every other form of human organizational activity. Examples of data sets include price indices (such as the consumer price index), unemployment rates, literacy rates, and census data. In this context ...

The mission statement of the Chemistry Literacy Project includes environmental and social justice. [26] Technological literacy is defined in a three-dimensional coordinate space; on the knowledge axis, it is noted that technology can be risky, and that it "reflects the values and culture of society".
