Top 5 Netflix series you need to watch

  1. The Flash

Young Barry Allen’s life stopped the minute his mother was murdered. The true killer never found, its mystery obsessed Barry, driving him to become a forensic scientist. Consumed by his work, he spent his life chained to his desk, solving every case that flew across it. But when a freak lightning bolt hits a nearby shelf in his lab, Barry receives super-speed, becoming the Flash. Now, he’ll race up buildings, across oceans, and around the world to get his man—while getting introduced to a world so much bigger than his old life of microscopes and cold cases.

Able to run at near light-speeds, his powers provide the ultimate caffeine kick: He can run up buildings, move so swiftly he phases through objects, create sonic booms with the snap of his fingers—and never need to order delivery. Despite his speed, Barry can become so obsessed with crime-solving he can still lose track of everything else around him, leaving the fastest man alive constantly running a minute behind.

  1. Riverdale

As a new school year begins, the town of Riverdale is reeling from the recent, tragic death of high school golden boy Jason Blossom – and nothing feels the same… Archie Andrews (KJ Apa) is still the all-American teen, but the summer’s events made him realize that he wants to pursue a career in music – not follow in his dad’s footsteps – despite the sudden end of his forbidden relationship with Riverdale’s young music teacher, Ms. Grundy (Sarah Habel). Which means Archie doesn’t have anyone who will mentor him – certainly not singer Josie McCoy (Ashleigh Murray), who is only focused on her band, the soon-to-be-world-famous Pussycats.

It’s all weighing heavily on Archie’s mind – as is his fractured friendship with budding writer and fellow classmate Jughead Jones (Cole Sprouse). Meanwhile, girl-next-door Betty Cooper (Lili Reinhart) is anxious to see her crush Archie after being away all summer, but she’s not quite ready to reveal her true feelings to him. And Betty’s nerves – which are hardly soothed by her overbearing mother Alice (Madchen Amick) aren’t the only thing holding her back.

When a new student, Veronica Lodge (Camila Mendes), arrives in town from New York with her mother Hermione (Marisol Nichols), there’s an undeniable spark between her and Archie, even though Veronica doesn’t want to risk her new friendship with Betty by making a play for Archie. And then there’s Cheryl Blossom (Madelaine Petsch)… Riverdale’s Queen Bee is happy to stir up trouble amongst Archie, Betty, and Veronica, but Cheryl is keeping secrets of her own. What, exactly, is she hiding about the mysterious death of her twin brother, Jason? Riverdale may look like a quiet, sleepy town, but there are dangers in the shadows…

  1. The good place

From Executive Producer Michael Schur (“Brooklyn Nine-Nine,” “Parks and Recreation” and “Master of None”) comes a smart, unique new comedy about what makes a good person. The show follows Eleanor Shellstrop (Kristen Bell, “House of Lies,” “Veronica Mars”), an ordinary woman who enters the afterlife and, thanks to some kind of error, is sent to the Good Place instead of the Bad Place, which is definitely where she belongs. While hiding in plain sight from Michael (Ted Danson, “CSI,” “Cheers”), the wise architect of the Good Place (who doesn’t know he’s made a mistake), she’s determined to shed her old way of living and discover the awesome (or, at least, the pretty good) person within.

  1. Once upon a time

For Emma Swan, life has been anything but a happy ending. But when she’s reunited with Henry – the son she gave up for adoption ten years ago – on the night of her 28th birthday, everything changes. The now 10-year-old Henry is in desperate need of Emma’s help because he believes from reading a book of fairytales that she’s the daughter of Snow White and Prince Charming – who sent her away from the Enchanted Forest to be protected from a curse that was enacted by the Evil Queen. Emma initially refuses to believe a word of Henry’s story but soon finds that his hometown of Storybrooke, Maine is more than it seems. Because it’s in Storybrooke that all of the classic characters we know are frozen in time with no memories of their former selves – except for the Evil Queen, who is Storybrooke’s mayor and Henry’s adoptive mother Regina Mills. Now, as the epic “Final Battle” for the future of both worlds approaches.

  1. Stranger Things

When Will Byers(Noah Schnapp) suddenly goes missing, the whole town of Hawkins, Indiana turns upside down. Many people are on the search for Will, including his mother Joyce(Winona Ryder), his brother Jonathan(Charlie Heaton), his friends—Mike(Finn Wolfhard, Dustin(Gaten Matarazzo), and Lucas(Caleb McLaughlin)–, the police chief Jim Hopper(David Harbour), and other notable people. But one thing leads to another, creating a supernatural trail. And things get even weirder when a little girl with a shaved head comes into the story.

After the mysterious and sudden vanishing of a young boy, the people of a small town begin to uncover secrets of a government lab, portals to another world, and sinister monsters. The boy’s mother, Joyce, desperately tries to find him, and is convinced he is in grave danger, while the police chief searches for answers. Trying to help find him, the boy’s friends discover a strange little girl, who is on the run from “bad men”.

5 riddles with answers


Question 1: There were 2 doors. Behind the 1 door, is hell and behind the other door, is heaven but you don’t know which door will take you to heaven. In front of them, there were 2 brothers, which is guarding the door. One of the brother always lie and the other one always tell the truth. Of course you don’t know who is lying and who is not. You only get 1 question to ask one of them to figure out which door leads to heaven. What question you might ask? Remember you only get to ask 1 question. it means that you can’t ask one question each of them. that will be 2 questions. You only ask 1 question to any of them and no more. How do you do that?


Question 2: Listen closely, for these for riddles are all connected. 1. How do you put a giraffe in the refrigerator? 2. How do you put an elephant in the refrigerator? 3. The lion king is having an animal conference, and all animals attend except one. Which animal does not attend? 4. You are on a stranded island that is inhabited by crocodiles. How do you get across without getting eaten alive?


Question 3: What goes back and forth constantly, but never in a straight line?


Question 4: Mr. Smith has 4 daughters. Each of his daughters has a brother.

How many children does Mr. Smith have?


Question 5: There is an ancient invention still used in some parts of the world today that allows people to see through walls.What is it?



Answer 1: Go up to one of the guy and ask this question, ” Hello, which door that your brother will point if I ask him which way is the heaven.” Then take the other door. Don’t enter the door that he was pointing. This question will work for both of them because if you ask this question to the truth guy, he will point the hell because he knows that his brother will point hell and if you asked to the liar, he’ll still point hell because he knows that his brother will point to heaven door, so he lied. That’s why you take the other door.


Answer 2: 1. Open the refrigerator, put in the giraffe, and close the door. This question tests whether you tend to do simple things in an overly complicated way. 2. Did you say, “Open the refrigerator, put in the elephant, and close the refrigerator”? Wrong Answer. Open the refrigerator, take out the giraffe, put in the elephant and close the door. This tests your ability to think through the repercussions of your previous actions. 3. The Elephant. The elephant is in the refrigerator. You just put him in there. This tests your memory. 4. You just jump into the water and swim across to the mainland. Have you not been listening? All the crocodiles are attending the Animal Meeting. This tests whether you learn quickly from your mistakes.


Answer 3: A pendulum.


Answer 4: He has 5 children, ll of the daughters have the same 1 brother.


Answer 5: A window.

History of Tic-Tac-Toe

Tic-tac-toe is a paper-and-pencil game for two players, X and O, who take turns marking the spaces in a 3×3 grid. The player who succeeds in placing three of their marks in a horizontal, vertical, or diagonal row wins the game.

Games played on three-in-a-row boards can be traced back to ancient Egypt, where such game boards have been found on roofing tiles dating from around 1300 BCE.

An early variation of tic-tac-toe was played in the Roman Empire, around the first century BC. It was called Terni lapilli (three pebbles at a time) and instead of having any number of pieces, each player only had three, thus they had to move them around to empty spaces to keep playing. The game’s grid markings have been found chalked all over Rome. Another closely related ancient game is Three Men’s Morris which is also played on a simple grid and requires three pieces in a row to finish, and Picaria, a game of the Puebloans.

The different names of the game are more recent. The first print reference to “noughts and crosses”, the British name, appeared in 1864. In his novel Can You Forgive Her? (1864) Anthony Trollope refers to a clerk playing “tit-tat-toe”. The first print reference to a game called “tick-tack-toe” occurred in 1884, but referred to “a children’s game played on a slate, consisting in trying with the eyes shut to bring the pencil down on one of the numbers of a set, the number hit being scored”. “Tic-tac-toe” may also derive from “tick-tack”, the name of an old version of backgammon first described in 1558. The U.S. renaming of “noughts and crosses” as “tic-tac-toe” occurred in the 20th century.

In 1952, OXO (or Noughts and Crosses), developed by British computer scientist Alexander S. Douglas for the EDSAC computer at the University of Cambridge, became one of the first known video games. The computer player could play perfect games of tic-tac-toe against a human opponent.

In 1975, tic-tac-toe was also used by MIT students to demonstrate the computational power of Tinkertoy elements. The Tinkertoy computer, made out of (almost) only Tinkertoys, is able to play tic-tac-toe perfectly.  It is currently on display at the Museum of Science, Boston.

Top 6 Serial killers

Warning: Some pretty messed up stuff ahead. *~*

  1. The Zodiac Killer

The killer fashioned this name for himself in taunting letters he sent to the Bay Area Press. He left ciphers to be decoded and out of the four he sent, only one was definitely solved. The killer operated in California in the late 1960s and early 1970s. His last letter said: Me- 37 and SFPD (San Francisco Police Dept.)- 0. He claimed to have killed 37 victims but the newspapers confirmed only 7. The case file is still open.


2. Donald Henry Gaskins: The Hitchhikers’ Killer

Gaskins has claimed to have killed between 80 to 90 people by torturing and mutilating them. He started killing in 1969, picking up hitchhikers on the coastal highways of the American South. A criminal associate witnessed him killing two young men and confessed to the police. He was sentenced to death which was later turned to life imprisonment without any parole. Gaskins added another murder to his name and became the only man to have ever killed an inmate on death row.


3. Tsutomu Miyazaki: The Human Dracula

He got more names due to his hideous acts. Some of them were The Otaku Murderer, The Little Girl Murderer or Dracula Miyazaki. The reason for this being that he abducted little girls, killed them and indulged in sexual activities with their corpses. On one occasion, he not only drank the victim’s blood but ate her hand as well. He also preserved body parts as trophies and sent postcards to the families describing the murder. His father committed suicide and Miyazaki was hanged in 2008, aged 45.


4. Ted Bundy: The Crazy Necrophile

Ted Bundy was an American serial killer, kidnapper, rapist, and necrophile. He operated in various states in the USA and confessed to killing 30 women. He revisited crime scenes and indulged in sexual acts with the corpses. Bundy decapitated at least 12 victims and kept their heads as trophies in his apartment. Aged 42, Bundy died on the electric chair in 1989. His own defence attorney said, “Ted was the very definition of heartless evil.”


5. Jack the Ripper aka Whitechapel Murder

The real killers or killer were never identified. The name came into being because the victims had organs missing and judging by procedure the killer seemed to have surgical experience. Jack the Ripper who was later believed to be a single person killed female prostitutes in the slums of London between 1888-91.


6. Luis Garavito: The Beast

Also dubbed by the media as the Le Bestia (The Beast), the Colombian is probably one of the world’s worst serial killers. He confessed to the torture, rape and murder of 147 young boys. But the number is believed to be over 300. He was found guilty on 139 counts, which should amount to 1,853 years in prison. But Columbian law limits it to 30, which is what he was sentenced to in 1999. He may be released earlier for cooperation and good behavior.

Why do cats purr?

Curling up with your favorite ball of fur as she purrs away is pretty close to heaven, at least for cat folk. Yet, hidden between those vibrations, that most appealing of domestic sounds remains wrapped in mystery, and even a little magic.

No one is certain exactly why cats purr, though there are a number of good guesses. The obvious observation is cats seem to purr when they’re pleased and feeling good. But that’s not always the case: Some cats also purr when they’re hungry, injured, or frightened. And most surprisingly, purring frequencies have been shown to stimulate bone regeneration—yes, bone regeneration.

Cats purr by using their larynx and diaphragm muscles, both as they inhale and as they exhale, although just how the central nervous system generates and controls those contractions isn’t yet understood. Early 19th century taxonomists thought cats could either purr or roar, and split the family Felidae along these lines—”purrers’ (subfamily Felinae) and ‘roarers’ (subfamily Pantherinae).

Today, though, taxonomists believe most cats can purr, with a few probable (though not certain) pantherine exceptions: lion, leopard, jaguar, tiger, snow leopard and clouded leopard. (Cheetahs and cougars? Yeah, they purr.)

So, why do it? If it’s a form of communication, it’s meant for those near and dear, since cats purr at a frequency and volume too low to travel far. Purring (and many other low-frequency vocalizations in mammals) often are associated with positive social situations: nursing, grooming, relaxing, being friendly.

More likely, though, purring is simply soothing, or self-soothing, as cats may also purr in stressful situations. In that case, purring would be akin to how humans soothe themselves by crying, laughing, distracting themselves, or even organizing their desk. Some veterinarians and cat enthusiasts have observed cats lying alongside each other and purring when one is injured (a behavior termed “purr therapy”), though scientific literature on the subject is scant.


Beyond being calming for the injured kitty, “purr therapy” may have bone healing properties. Domestic cats purr at a frequency of about 26 Hertz, in a range that promotes tissue regeneration. That’s not as crazy as it sounds: High-impact exercise promotes bone health for the same reason, because bones respond to pressure by making themselves stronger.

In their natural setting, cats spend a lot of time lying around waiting to hunt, so purring may stimulate bones so that they don’t become weak or brittle. In fact, purr-like vibration devices have been patented for potential use in therapy, and some researchers have proposed strapping vibrating plates to astronauts’ feet during long space flights to retain bone density.

Such reasons to purr are by no means exclusive. “All behavior depends on history, context and expectation,” says Tony Buffington, a cat expert and veterinarian at Ohio State University. “So it’s naive to think that cats can only purr for one reason—it’s like thinking that people can only laugh for one reason.”

Humans can laugh out of joy, a desire to be polite, when surprised, in discomfort or in derision—and only context will tell an onlooker which is going on.

It would be easier to tell what function the low-frequency rumbles play if we could “de-purr” a cat. But, Buffington notes, what are you going to do, cut off its air supply? You’d lose a cat and learn nothing. If you want to know why your particular favorite feline is purring, Buffington suggests paying attention to what prompted the purring and what it leads to.

Did you just arrive home to be greeted by your cat purring and rubbing against your leg? He might be happy to see you. Is your cat pestering you around dinnertime, purring insistently? It may be hungry. (Cats seem to purr with greater urgency when hungry.) Is he purring at you through YouTube? Maybe he’s encouraging you to finish the story you’re writing.

Where does a plant’s Mass Come From?

  Have you ever wondered where plants get their mass? All those leaves and branches have to come from somewhere, but where? It turns out that the main ingredients for plant growth are water, air, and energy.Water, Air (CO2), energy are needed for plant mass.

Where plants get their mass.

  The Story of Air

carbon dioxide

The molecule carbon dioxide is made of one carbon atom and two oxygen atoms.

The air around you may seem empty, but it’s not.

Air is made of tiny bits that we call molecules. If you had enough air molecules, you could even weigh them.

Two of the molecules in air are oxygen and carbon dioxide. You may think oxygen is the most important molecule—we need it to live. But carbon is important too. All living things on Earth are made of carbon.

If you removed the water from our bodies, you would find that carbon makes up most of the rest of our weight, or mass. The same is true for plants.

soil sun and water

Plants don’t get carbon from any of these sources.

We get carbon from our food, but where do you think plants get carbon? They don’t get their carbon from the soil, or from the sun, or from water.

Plants pull carbon out of the air.


Are Plants Made from Thin Air?

Inputs for photosynthesis

Plants need energy from the sun, water from the soil, and carbon from the air to grow.

Air is mostly made of nitrogen, oxygen, and carbon dioxide. So how do plants get the carbon they need to grow? They absorb carbon dioxide from the air. This carbon makes up most of the building materials that plants use to build new leaves, stems, and roots. The oxygen used to build glucose molecules is also from carbon dioxide.

Water is another important material plants need to grow, and they get it by absorbing it through their roots. Water is made of two hydrogen atoms and one oxygen atom. The hydrogen in water is used to help build glucose molecules.

A plant can be up to 95% water. Think of the water as the filler they use between carbon structures. If we take away the water from a plant though, and look at just the dry material, a large majority of that material comes from thin air.

Plants also need tiny bits of vitamins and minerals to grow properly, which they get through their roots.

Plants need a lot of energy to take care of their cells and to build new ones so they can grow. Plants get their energy from the sun.

The Carbon Story

cross section of a leaf showing stomata

Plants absorb carbon dioxide through small openings called stomata that are on the surface of the leaf.

If we zoom in on a plant leaf, so close that we can see the cells, we’ll find tiny openings called stomata. Stomata are holes made from spaces between special cells. These holes are where plants absorb carbon dioxide from the air.

Once inside the leaf, the carbon dioxide can enter plant cells. Inside the plant cells are special cell parts called chloroplasts, where photosynthesis takes place.

Plant cell illustration

Circled inside the plant cell is one of hundreds of chloroplasts that live within the cell.

Plant cells look green due to molecules in the chloroplasts that reflect green light. There are many, many chloroplasts in every green plant cell. Most of the rest of the cell usually looks clear.

In the chloroplasts, carbon, oxygen, hydrogen, and energy are used to make a sugar called glucose. The whole process of making glucose is called photosynthesis.


Molecules of glucose join together to form cellulose.

Next, glucose molecules combine to form long chains called cellulose. Cellulose is then used to build plant structures, like cell walls.

leaf growth

As more cells divide, the plant’s leaves, stems, and roots can grow larger.

These structures and the materials they hold are also built with water.

When new cell structures are built, cells can grow and divide, making new cells. These new cells make for new plant growth. This lets the plants get bigger.

 So if you are creating a cookbook of life and want to include a recipe for plant growth you would add the following.

water tree

  • Water, which can make up to 95% of the weight of a plant, enters the plant through its roots.


  • Carbon, which makes up the most of the rest of the plant, comes from the air and enters the plant through holes in its leaves.


  • Oxygen from carbon dioxide, and hydrogen from water, enter through the leaves and roots, and are used to make glucose.


  • Energy, which the plant needs for photosynthesis to work, is absorbed from sunlight.

recipe for plant growth

In order to grow, plants need water, carbon dioxide (from air), and energy from sunlight.

Why do leaves change color in the fall season?

In some areas of the world, the weather changes in the fall, making the air turn cold. During this time, many leaves also change colors. Why does this happen?

image of dormant tree

Deciduous trees drop their leaves in winter. Image by Paul Buckingham.

First let’s think about why some trees drop their leaves before winter. In the winter, it would take a lot of energy and water for plants to keep their leaves healthy. But winter is cold, dry, and usually there isn’t much sun (which helps give plants energy). So, instead of trying to keep their leaves, some plants drop their leaves and seal the spots on their branches where the leaves had been attached.

How is this related to what makes leaves colorful?

Leaves are colored by molecules called pigments. The pigment that causes leaves to be green is chlorophyll. Chlorophyll is important for plants to make food using sunlight. During spring and summer when there is plenty of sunlight, plants make a lot of chlorophyll.

In autumn when it starts to get cold, some plants stop making chlorophyll. Instead, those plants break down chlorophyll into smaller molecules. As chlorophyll goes away, other pigments start to show their colors. This is why leaves turn yellow or red in fall.

orange colored leaf

In fall, plants break down and reabsorb chlorophyll, letting the colors of other pigments show through. Image by Sander van der Wel.

The color change usually happens before the leaves fall off of the tree. Why might that be? It takes a lot of energy to make chlorophyll. If the plants break down the chlorophyll and move it out of their leaves before the leaves fall, plants save energy. The plants can reabsorb the molecules that make up chlorophyll. Then, when it’s warm and sunny enough to grow again, the plants can use those molecules to remake the chlorophyll. That way the plants don’t have to make chlorophyll from scratch.

There are other pigments in leaves called carotenoids. Carotenoids are yellow and orange. Anthocyanins are other plant pigments that are only made in the fall. These pigments cause red, pink, or purple colors. Anthocyanins also protect leaves from being eaten or getting sun burned.

So the different colors in leaves are caused by changes in the pigments. When the weather changes, some plants break down all the green pigment. This lets beautiful yellows, oranges, and reds come through in the fall.
