‘My land has palm trees where the thrush sings / Sin A, cosine B…’ you probably know how to complete this sentence to this day, but does memorizing help with your studies? See the explanations. Songs and tricks help students memorize formulas for exact subjects Disclosure 🌴 If it were possible to make an exclusive playlist of the life of college students, some renowned “hits” would be at the top of the charts: “My land has palm trees where the thrush sings / Seno A, cosine B / Sine B, cosine A”; “One two three; three, two one / All about two / Square root where there isn’t one.” The verses may seem strange and the phrases “How soft”, “What a trick”, “God sees everything” sound random to those who are not about to face a marathon of university entrance exams. But even an “Ice Cream” and a “Sorvetão” mean more than just a refreshment in the heat for entrance exam candidates. 🍦 There are songs and tricks that help them memorize some of the many math, physics and chemistry formulas. g1 asked professors Rodrigo Serra, Roberto de Alessandri and Pietro Escobar, from Curso e Colégio Oficina do Estudante, for some examples used in class, which are listed below. According to neuroscientists, before and during the test, when anxiety is high, they can be a “trigger” to remember the material studied. 🧑‍🔬 But, after all, why is it easier to decorate formulas with music and tricks? 🤔 🎵 Music to ‘anchor’ According to the doctor, neuroscientist and professor at Unicamp Doctor Li, this happens because memory is usually related to things around us and is also impacted by affective issues. “If I ask you what you ate on your last birthday, it’s very likely that you’ll remember that you ate a delicious cake, something like that. But if I ask you what you ate on Monday three weeks ago, a date that may even be closer, you will have difficulty remembering”, explains Doctor Li. 🎂 When talking about music, specifically, they represent another memory support element. “Songs and phrases serve as an anchor for you to access information.” ⚓ Reproduction of the brain, in an Unsplash file image Biologist and neuroscientist Alexandra Resende explains that this occurs because music relates brain processes to pleasure and pleasant things. 🌉 Furthermore, it builds a bridge with reality to work on Working Memory, which is located in the frontal lobe, a brain region just behind the forehead. It is in this area, according to the neuroscientist, that life experiences are stored: everything we see, hear, smell, taste and feel is there, integrated and ready to be used to understand new things. 🧠 “When you use a song, you take something that the person knows and add something that is profound. This generates pleasure and helps working memories function more efficiently”, says Rezende. Some examples 💿 Mathematics Here are the classic songs. Professor Rodrigo Serra, from Curso e Colégio Oficina do Estudante, listed his main ‘hits’, starting with the number one in the charts: the mix of ‘Canção do Exílio’, by Gonçalves Dias, mixed with trigonometry to help students do addition and subtraction of arcs. And there are two versions. The first, to calculate the sine of the sum of two angles [sen (a+b)] = sin(a) · cos(b) + sin(b) · cos(a)]. “My land has palm trees Where the thrush sings Sin A, Cosine B Sin B, Cosine A” To calculate the cosine, whose formula is cos(a + b) = cos(a) . cos(b) – sin(a) . sen(b), changes a little: “My land has palm trees Where the thrush sings Coça A, Coça B Changes the sign without knowing” Still on the trigonometry ‘album’, another ‘single’ stands out to help students memorize the reasons trigonometric measurements of notable angles (30º, 45º and 60º). “One, two, three Three, two one Everything about two Square root where there isn’t one” Trigonometric ratios of notable angles Without missing a beat, there’s still room for tricks. After all, what about the tangent of the sum of two angles? To remember that tg(a+b) = (tga+tgb)/(1-tga.tgb), it’s simple: “There are people in bathroom A, There are people in bathroom B, Um, there are people in bathroom A and in the bathroom B” Geometry also has its tricks. For example, according to Euler’s Law, the sum of the vertices and faces of a rectangular polygon is equal to the sum of the edges of the form plus two (V + F = A + 2). Difficult? Nothing more than remembering that it is possible to have a Happy Life for two. And there is even a trick with an international diva. To calculate the distance between the point and the straight line (Dpr), you can memorize that you found Beyoncé on top of the root of a square pumpkin, for example [Dpr = (axo + byo + c) / √(a² + b²]. The equation of the straight line is YoYô, Mixoxô [Yo = m (x – xo)]. ✍️ Physics Physics is not very musical, but it has several tricks with words and phrases — there are even two religious ones, for those who want to turn to the divine during the test. The tips come from physics professor Roberto de Alessandri, from the Oficina do Estudante Course and College. 💡 When it comes to Uniform Movement (MU), to calculate the position of a piece of furniture, the formula is S = so. + vt And to remember this formula, just remember a beautiful “ice cream”. When calculating the distance covered by this piece of furniture, remember that “God sees everything” (d = vt). 🙏 👀 When analyzing Uniformly Varied Motion (MUV), speed is calculated with V = vo + at To make it easier, “I saw you for nothing”. An “ice cream” 🍨 helps you remember the formula for calculating the position of a piece of furniture in the MUV. The formula is S = so + vo.t + at²/2. “What a trick”, right? Yes, and this can help you remember the formula to calculate sensible heat in Calorimetry 🔥, because the formula is Q = mcΔt. And yes, it’s a breeze! The latent heat calculation is Q = mL (“how soft”). A formula that serves both physics and chemistry is the Clapeyron Equation, which shows the thermodynamic state of gases. 🎈 The calculation is PV = nr t (For you, I have never prayed so much). 🧲 Finally, in terms of electromagnetism, there is a game that can even make you hungry. The radius of the trajectory of a charge thrown perpendicularly into a magnetic field is R = (mv) / (qb). In other words, “Rabib, give me a kibbeh”. 🔊 Chemistry The discipline is the pinnacle of musicality, including “Rap da Pilha”, 🔋– many consider it, in fact, funk — which ended up on the Jô Soares Program in 2013. 🌃 The hit created by the teacher Carioca Silvio Predis is even available on digital music platforms, such is his success. Check the lyrics and read in rhythm with the ‘beat’: “Come, come, come, come, come, come In oxidation the anode is negative Where corrosion occurs Corroded electrode concentrating the solution The electrons leave for the big cathode And the nox goes going up A kiss in the heart” Silvio Predis participates in this Thursday’s Programa do Jô Photo: TV Globo/Programa do Jô Success in the music charts for chemistry enthusiasts, Pietro Escobar, teacher of the subject at the Course and Colégio Oficina do Estudante, always recommends the songs adapted for the students. “He [o Silvio] He made me a funk song that lasted a minute and a half that sums up one of the most difficult subjects he has. (…) The music is impeccable, it doesn’t have a flaw. I looked for a defect and couldn’t find it.” The professor from Campinas (SP) is known for his stories in class and a “re-recording” of a composition already well known in the area, complete with a mix of rhythms. It is the music of solubility. “Nitrites, nitrates and acetates are soluble… Ammonium and alkaline salts are also… Chlorides, bromides and iodides are also Hg, Pb, Ag (mercury, lead, silver) Sulfates are the most boring.. . They do not dissolve even with agitation… Neither Ca, Sr and Ba, nor Pb will dissolve (calcium, strontium, barium, lead)” ⚠️ Pay attention to an important detail: the rhythm is the same as “The carnation fought with the rose”, sung in falsetto until the verse (mercury, lead, silver), when it is necessary to make a deep voice à la heavy metal because these are heavy metals. Unfortunately, the teacher did not authorize g1 to play the audio in this subject citing reasons of shyness, but you can imagine… Person studying Tirachard Kumtanom ‼Memorizing is not learning‼ All the examples are valid memorization strategies, but memorizing something is just the first step in the learning process. In other words, there is no point knowing the formula and not knowing how to use it. “To learn, you need to consolidate your memory”, says Doctor Li. No, formulas, by themselves, are not consolidated memories. ❌ They are just superficial information. “Knowledge is in depth”, says biologist and neuroscientist Rezende. In the information age, it can be common to think that more is better. But that’s not exactly how the brain works. “You run the risk of having a lot of information and not knowing how to talk to it, that is, reason based on it”, says Rezende. The reasoning that generates the answer to a question, for example, comes from acquired knowledge. And knowing something, according to the neuroscientist, means accessing different brain areas to integrate a conclusion. ✅ 📚 Therefore, the mathematics teacher of the Student Workshop course issues the same warning to students. “No one transmits knowledge, knowledge is built”, states Rodrigo Serra.

Paying attention in class is obvious, but this is not enough from the point of view of neuroscience, nor of education. It’s nothing new: for the memory to consolidate and be there, available in the long term, repetition is necessary. It’s the infallible recipe for reviewing material and solving exercises. In other words, it is necessary to study beyond the classroom, but it is also essential to go beyond studies. The good news is that this doesn’t mean anything crazy. “For the information to be consolidated, the person needs to sleep. Because it is during sleep that it is consolidated in the brain”, explains doctor and neuroscientist Doctor Li. 😴 Therefore, the message to insomniac college students is clear: spending sleepless nights studying is a waste. Literally, you have to sleep to get into college. “It has to be regular sleep, you can’t leave it until later. The sleep you lost is lost. You can’t recover”, says Doctor Li. While resting helps (a lot), moving is also essential, even to prevent the famous “whiteout” at the time of the test. The neuroscientist explains that the stress of the entrance exam, for example, demands a lot from the body, which needs to be strong to ‘withstand the pressure’. 💪 “For you to have a strong body, you need to do physical activity. It keeps the brain functioning well,” he says. Doctor Li explains that the brain is a machine that needs to be well looked after. And this care includes, precisely, good sleep, exercise and good emotions and thoughts. In fact, to guarantee the last part, there is also a strategy that does not involve spending hours on end concentrating on studying. 👯 “We are social beings. Students should not deprive themselves of social interaction. It’s good for our mental health,” he says. VIDEOS: everything about Campinas and the region See more news from the region on g1 Campinas
