The question is: is light ray from the sun a matter?
To start with, matter is anything that possesses this two criteria :
1) mass
2) ability to occupy space.

Facebook, Google and other tech firms have agreed a code of conduct to do more to tackle the spread of fake news, due to concerns it can influence elections, the European Commission said on Wednesday.
“Intended to stave off more heavy-handed legislation, the voluntary code covers closer scrutiny of advertising on accounts and websites where fake news appears.
“Thereby working with fact checkers to filter it out,’’ the commission said.
However, a group of media advisors criticised the companies, also including Twitter and lobby groups for the advertising industry for failing to present more concrete measures.
Brussels, with EU parliamentary elections scheduled for May, is anxious to address the threat of foreign interference during campaigning.
Belgium, Denmark, Estonia, Finland, Greece, Poland, Portugal and Ukraine are also all due to hold national elections in 2019.

Google will resume accepting cryptocurrency-related online advertising after previously banning such ads earlier this year, according to a report from CNBCtoday. Lifting the ban will allow regulated crypto exchanges to purchase ads through Google’s platform in the US and Japan starting next month.

Who was the greatest physicist ever—Isaac Newton or Albert Einstein?

1) Elevators and Apples

I’ll give this to Einstein. He had arguably the most brilliant idea to ever arise from the gelatinous pile of neurons that we call brains. While sitting at his desk in the Swiss patent office, Einstein had what he would later describe as his “happiest thought.” Einstein had been trying to understand how gravity fit into spacetime, that hybrid of x’s and t’s that he himself had invented only a few years before.
While pondering a person floating in a box in outer space (don’t ask), Einstein suddenly came to the realization that gravity could be understood as a curvature of spacetime (and vice versa). Exactly how he made that leap is grist for another post. Weird as it may sound, this was his brilliant realization, and later experiments confirmed it is correct. Gravity = curved spacetime. No gravity = flat spacetime.

Mechanical engineering is one of the broadest and oldest disciplines of engineering; it is a branch of engineering that uses physics, mathematics and material science principle to design, evaluate, manufacture and maintain machines, devices, mechanical equipment and frame works. They also implements components to monitor and control their product’s performance and status. They are also essential in military hardware production and electrical power generation.
Mechanical engineers uses tools such as computer-aided design (CAD), computer-aided manufacturing (CAM) and product life cycle management to design and analyze manufacturing plants, industrial equipment and machinery, heating and cooling systems, transport systems, aircraft, watercraft, robotics, medical devices, weapons and others. It is a branch of engineering that involves the design, production and operation of machinery.

At first, what do we mean by technical report writing; a technical report is a formal report designed to convey on-going or a completed work emanated from investigation, information, research or study of technical issues, in a clear and easily accessible format. The work may be a laboratory experiment, library research, design work, construction work, mathematical analysis or a combination of these.
A report is normally prepared because some work has been done and somebody else needs to know the outcome, either because they have asked for it or because the writer wants to inform or persuade.

They by, technical report writing is very essential for undergraduates, postgraduates and also professional personnel to be able to share their technical outcome to the audience.
We are going to look at the features a good technical report write-up must possess in the next division.

Characteristics and features of a good technical report writing

1. A good technical report must be written and arranged in a definite order – the main order is to separate it and break it into the various divisions and then sub-divide each of the divisions.

Crystals can be defined as an ordered, repeating, 3-dimensional arrangement of atoms within a material. Essentially, all metal, certain polymers and a significant fraction or ceramics materials possess crystalline structure when solidify. The ordered atomic arrangement over a long range of many atomic distances is due to the atomic coordination within the material. Also, the ordered pattern sometimes controls the external shape of the crystal. For instance, the planar surfaces of gems, quartz (SiO2) crystal and even ordinary table salt (NaCl) are all external manifestations of internal crystalline arrangements.
The coordinating number (CN); simply refers to the number of first neighbors, which an atom has.

Crystal System

Specific patterns are formed as atoms and molecules are coordinated with neighbors to form a solid. There are basically seven crystal systems that out of which a material may exist. These are summarized below with their geometric properties.

Twitter has told an undisclosed number of users their private messages may have been leaked to third-parties for more than a year.
The software “bug”, which has since been fixed, involved direct messages between users and businesses that offer customer services via Twitter.
Affected users are being notified via a message that appeared when opening the app or logging on to Twitter's website.
"The issue has persisted since May 2017," Twitter said.
The company said it had resolved the issue immediately upon discovering it, on 10 September.

Cloud computing is shared pools of configurable computer system resources and higher-level services that can be rapidly provisioned with minimal management effort, often over the internet. Cloud computing relies on sharing of resources to achieve coherence and economies of scale, similar to a public utility.

It is the on-demand delivery of compute power, database storage, applications, and other IT resources through a cloud services platform via the internet with pay-as-you-go pricing.

Cloud computing provides a simple way to access servers, storage, databases and a broad set of application services over the Internet. A Cloud services platform such as Amazon Web Services owns and maintains the network-connected hardware required for these application services, while you provision and use what you need via a web application.


Examples of cloud computing
Cloud computing underpins a vast number of services. That includes consumer services like Gmail or the cloud back-up of the photos on your smartphone, though to the services which allow large enterprises to host all their data and run all of their applications in the cloud.

Apple just removed its number one paid utility in the Mac App Store, Adware Doctor, after it was found to be secretly recording users’ app data and browser history and sending it back to a server located in China, as spotted by 9to5Mac.
Apple was notified a month ago by a security researcher, but it only removed the app today. From looks alone, the app appeared legit, with plenty of five-star ratings and approval from Apple. It was listed alongside vetted apps like Final Cut Pro and Logic Pro X.
Adware Doctor was supposed to scan Mac computers for malware and remove suspicious files. It originally pretended to be a dupe of Malwarebytes’ Adware Medic app,
