Week 12 (12.01-18.01.15) Are you an early bird or a night owl ?

Owls are nocturnal creatures. They’re wide awake at night and they sleep during the day. If this sounds like bliss to you, then, like about 20 percent of the population who find themselves most active at around 9 pm, you may fall into the same category as our feathered friend. Night owls often have difficulty waking up in the morning, and like to be up late at night.  Studies of animal behaviour indicate that being a night owl may actually be built into some people’s genes. This would explain why those late-to-bed, late-to-rise people find it so difficult to change their behaviour. The trouble for night owls is that they just have to be at places such as work and school far too early. This is when the alarm clock becomes the night owl’s most important survival tool. Experts say that one way for a night owl to beat their dependence on their alarm clocks is to sleep with the curtains open. The Theory is that if they do so, the morning sunlight will awaken them gently and natura...

Week 3 [09.04-15.04.2018] Can we trust Facebook with our personal data?

Facebook is one of the most popular and biggest (if not the most popular and biggest) social media platform in the world. It is estimated that there are more than 2.13 billion monthly active users. Around 50% of them are daily active mobile users. All these daily requests store huge amount data that can be later processed. But what data does exactly Facebook collect and how is this data used? Some of you may already know about recent Facebook's data privacy scandal involving London-based data mining and analytics firm Cambridge Analytica that misused user data of estimated 50 million Facebook users. As result, Facebook had to suspend from the platform Strategic Communication Laboratories (SCL) along with its political partner Cambridge Analytica. Companies ran data operations for Donald Trump’s 2016 presidential election campaign and are widely credited with helping Trump to influence voters on Facebook. While some details are still not known, Facebook’s disclosure suggests t...

Week 3 [ 21-27.10.19] Memory Capacity of the Human Brain

What Is the Memory Capacity of the Human Brain? In the age of information technology, we are used to the fact that any information should occupy a certain amount of memory in storage. And since memories are information, then sooner or later they must fill the amount of memory in a person’s head. But the human brain is not a hard drive where you can write information in free blocks.

Each time, recalling a past event, we activate the neural connections associated with it. We can say that having a finite number of neurons (according to researches it is about 100 billion cell nuclei) a finite number of connections can be created inside the brain. This, in turn, might me...
