The controversy of gray or pink sneakers was one of the curious topics highlighted in 2019. The image, shared on messengers like WhatsApp and social networks, caused great confusion in people who could not identify the real shade of the shoes. Originally shared in 2017, the photograph reappeared, this time, accompanied by a possible scientific explanation of its effects.

According to the shared current, the reason why some people identify gray or pink in sneakers was in a supposed predominance of brain activity on one side of the brain. However, as we found at the time, the theory has no scientific basis. The reason for the color confusion is linked to an optical illusion effect. As we also discovered, the free PicsArt app has a feature that can help users discover the real color of the object.

A supposed image of the beach also generated great speculation on the web because it was originally an optical illusion. The photograph was originally posted on Twitter and generated a series of shares. The original post, created by the user @nxyxm, also contains the complementary phrase «but this is not a painting, but the bottom part of a car door that needs to be repaired».

Muhammad Nayem, owner of the @nxyxm profile, told dnetc that he took a random photo of his car and that, after sharing it on Twitter, he realized the optical illusion created. «At first, few people understood the image, but after so many comments and theories, they were intrigued and started calling it ‘the best illusion image of all time,» says the Pakistani fashion designer.

The optical illusion known as Gato or Corvo even managed to deceive the Google search engine algorithm. The image appeared on a Twitter share of the user @RobertMaguire_ that said «This photo of a crow is interesting because … it’s actually a cat». The confusion was created when the animal, when posing for a photo, bent its neck causing its ear to assume, in the illusion, the shape of a beak. In addition, one eye was in the same place where the bird’s eyes would be.

A closer look could see the illusion without much difficulty. Still, Google’s search engine, which uses landmarks, lines and textures to identify images, was misled and presented the photograph as a crow. Robert Maguire later admitted that the photo is not his own and that it was just shared from a Reddit forum.

The image of a crow being petted that was shared on Twitter by the Imgur service caused a great deal of confusion because it also contained an optical illusion. The impression is caused when the rabbit’s snout, head and ears take on the profile of a crow. The original post was shared with the caption «I think there is something wrong with this rabbit» (free translation from English).

According to Dan Quintana, who shared the video, in an interview with the CNET website, the reason for sharing the image on his profile is the fact that the «bird / rabbit» illusion is well known in psychology and philosophy studies. Other Twitter users noticed the reference and posted in response to the illustration cited by the scientist. Originally published in a German magazine in 1892, the image has no definite author, but it was used by American psychologist Joseph Jastrow as proof that optical illusions can be caused by people’s mental activity.

The equation “8 ÷ 2 (2 + 2)” published on Twitter, caused controversy when users debated about the real mathematical result in resolution. In fact, there are two solutions for the account and it was this detail that made the post go viral quickly among users of the microblog. According to Mike Breen, spokesman for the American Mathematical Society, the way the problem is written can cause common confusion in mathematical situations “As it is written, it is ambiguous. In mathematics, there are often ambiguities. Mathematicians try to make rules as precise as possible, ”said the expert.

Breen also explains that how a person learned math is also critical to solving the equation. The PEMDAS and BODMAS methods differ in the order of multiplication and division. Thus, a supporter of the PEMDAS scheme would reach result 1, while using the BODMAS method the answer would be 16.

Sco Pa Tu Manaa is an expression originally used in the song “Daavi Ne Ba”, released by Ghanaian singer Kawoula Biov in partnership with the artist Patapaa, known for creating meaningless expressions in his raps. The curious phrase went viral on Twitter with posts that accompanied nostalgic photos or that refer to everyday situations, as a synonym for expressions “what does that remind you of?” and «what is your opinion on this?»

However, on the Know Your Meme website, “Sco Pa Tu Manaa” informs that the expression has a Hawaiian origin and that its meaning is “I’ll hit you”. Google Translate, on the other hand, offers the following translation: “you will find it interesting”. Still, Twitter users assimilated the phrase as slang that means “what is your opinion on this?” or “what does that refer you to?”.
