The law of conservation of mass states that the total mass present before a chemical reaction is the same as the total mass present after the chemical reaction; in other words, mass is conserved.

What happens to matter when it undergoes chemical changes? The Law of conservation of mass says that "Atoms are neither created, nor distroyed, during any chemical reaction." Thus, the same collection of atoms is present after a reaction as before the reaction. The changes that occur during a reaction just involve the rearrangement of atoms.

Edward Snowden disclosed in 2013 that the US government's Upstream program was collecting data people reading Wikipedia articles. This revelation had significant impact the self-censorship of the readers, as shown by the fact that there were substantially fewer views for articles related to terrorism and security.[12] The court case Wikimedia Foundation v. NSA has since followed.

Google's move to release location data highlights concerns around privacy. According to Mark Skilton, director of the Artificial Intelligence Innovation Network at Warwick Business School in the UK, Google's decision to use public data "raises a key conflict between the need for mass surveillance to effectively combat the spread of coronavirus and the issues of confidentiality, privacy, and consent concerning any data obtained."

Liberal and Conservative Representations of the Good Society: A (Social) Structural Topic Modeling Approach

the absence of a social contract

We have to recognize that prior to Web 2.0 and social media, “the media” often connoted “mass media,” broadcast from the few to the many.

Thus mass collaboration is more refined and complex in its process and production on the level of collective engagement.

One possibility is the American preoccupation with fame. Studies have found that Americans are more interested in fame than people of other nationalities are. A 2007 Pew Research survey of 18- to 25-year-olds found that about half said that getting famous was a top priority for their peers. Television shows increasingly promote fame as a value, research has found, and pop lyrics are becoming more narcissistic. A 2010 review of research studies found that modern college students display less empathy than students of the late 1970s. These studies fit a general pattern of research showing that narcissism is on the rise. Simultaneously, Lankford said, the line between being famous and infamous is blurring. Scientists looked at the covers of People magazine issues dating from 1974 to 1998, and found that cover stars were increasingly featured for bad behavior — cheating, arrests, crime — rather than good acts (though there was a slight shift toward positivity after the Sept. 11 terrorist attacks), according to their 2005 report.

Let Σ0be a compact strictly convex hypersurface inRn,Xbe the position vector ofa point on Σ0, and letNbe the unit outward normal of Σ0atX. Let Σrbe the convexhypersurface described byY=X+rN, withr≥0.

Patrick Ball—a data scientist and the director of research at the Human Rights Data Analysis Group—who has previously given expert testimony before war crimes tribunals, described the NSA's methods as "ridiculously optimistic" and "completely bullshit." A flaw in how the NSA trains SKYNET's machine learning algorithm to analyse cellular metadata, Ball told Ars, makes the results scientifically unsound.

There are approximately 300M guns (including roughly 6 million AR-15 style rifles) in the possession of 120M gun owners in the US. Yet the gun murder rate has declined from 7.3/100k in the 70's to roughly 3/100k in 2014.

I am really interested in the possibilities, the prospect of bipartisan legislation around the criminal justice system -- something that I think directly speaks to some of the themes I mentioned on Friday. And we’ve seen some really interesting leadership from some unlikely Republican legislators very sincerely concerned about making progress there.
