IMPI YABOMDABU ISETHUNJINI – JC Buthelezi

By Sandile MHlophe -
 ISINGENISO  Umyalezo yilokho umbhali asixwayisa noma aseluleka ngakho enovelini/yisifundo esitholakala uma sifunda inoveli. Umyalezo uchaza ukuthi umbhali ubehlose ukusazisani ngokubhala le ndaba. Umyalezo wale noveli uthi: Ukungawazisi umndeni wakho kuba nemiphumela engemihle empilweni yakho. UMZIMBA  UBafana  Ukuba yisifundiswa kukaBafana kwenza ukuba uBafana awubukele phansi/angawazisi umndeni wakhe. La maphuzu alandelayo akhombisa izinto ezenziwa uBafana ukungawunakekeli umndeni wakhe:  • UBafana uxosha umalume wakhe kabuhlungu uma ezocelela izingane zikaLinono indawo yokuhlala.  • Ukungazwani kukaBafana noPoppie kwenza u-Euthenasia eqe ekhaya.  • UBafana akanasikhathi sezingane zakhe.  • UBafana uba nomona ngokuzithuthukisa kukaPoppie ngokufunda umtshela nokuthi akayeke ukufunda.  • Ukuhluleka kukaBafana ukubhekana nezinkinga zasemzini wakhe kwamenza walifulathela ikhaya. Umphumela wokungawazisi umndeni empilweni kaBafana: • Udlala izin...

 Umlingiswa ongummeleli emdlaweni othi, Kudela Owaziyo. ISINGENISO  Ummeleli ngumlingiswa oyiqhawe lomdlalo.  Indaba yonke incike kuye. Yize engekho kwezinye izehlakalo kodwa ziyamthinta ngandlela thize. Indaba yonke imayelana naye. Ubhekana nenkinga ethile ashikashikeke ezama ukuyixazulula. Kuyenzeka aphumelele noma ehluleke.

BENGITHI LIZOKUNA – NG Sibiya

By Sandile MHlophe -
 BENGITHI LIZOKUNA – NG Sibiya Umbuzo: Xoxa ngempumelelo yombhali ekudluliseni umyalezo othi: 'Izinqumo esizithathayo ngempilo yethu zingaba nemiphumela engemihle empilweni yethu neyabanye abantu' ubhekise kulaba balingiswa: uMhlengi/Mahlengi, uNontobeko, uXolani, noNgidi kule noveli ethi, Bengithi Lizokuna. ISINGENISO Umyalezo yilokho umbhali asixwayisa noma aseluleka ngakho enovelini/yisifundo esitholakala uma sifunda inoveli. Umyalezo uchaza ukuthi umbhali ubehlose ukusazisani ngokubhala le ndaba. Umyalezo wale noveli umayelana nokuthi izinqumo esizithathayo ngempilo yethu zingaba nemiphumela engemihle kwabanye abantu nakithina uqobo. Ohlolwayo angasebenzisa la maphuzu alandelayo namanye amayelana nomyalezo kule noveli.

Do we have free-will?

By Sandile MHlophe -
 Are you free?  we often think we are free but are we really free? this question sounds so simple yet it is actually not. What does it even mean to be free? Well in this post I will explain to the best of my knowledge what is free will and whether we have it or not. can you escape fate? Let's consider the story below: When Thabiso was born a prophet foretold that he would grow up to kill his father and then marry his mother. His father fearing for his life decided to leave the baby in the wilderness with the hope that he will die, thefore the prophecy will not come  true. The baby was found by another couple, and grew up knowing them as his parents. The boy heard of the prophecy, not knowing his adopted and because he loves his father(adopted) he decided to go away from his family to avoid the prophecy. In the way he met and killed a man and then felt bad for the wife of this man, he decided to marry her. The man he met is in fact his fat...

Gravity and orbit - Simulation

By Sandile MHlophe -
  Topics Gravitational Force Circular Motion Astronomy Description Move the sun, earth, moon and space station to see how it affects their gravitational forces and orbital paths. Visualize the sizes and distances between different heavenly bodies, and turn off gravity to see what would happen without it! Sample Learning Goals Describe the relationship between the Sun, Earth, Moon and space station, including orbits and positions Describe the size and distance between the Sun, Earth, Moon and space station Explain how gravity controls the motion of our solar system Identify the variables that affect the strength of gravity Predict how motion would change if gravity was stronger or weaker

Wave interference - Simulation

By Sandile MHlophe -
  Topics Interference Double Slit Diffraction Waves Description Make waves with a dripping faucet, audio speaker, or laser! Add a second source to create an interference pattern. Put up a barrier to explore single-slit diffraction and double-slit interference. Experiment with diffraction through elliptical, rectangular, or irregular apertures. Sample Learning Goals Make waves with water, sound, and light and see how they are related. Design an experiment to measure the speed of the wave. Create an interference pattern with two sources, and determine the ways to change the pattern. Find points of constructive and destructive interference by eye and by using the detectors. Put up a barrier to see how the waves move through one or two slits. What sort of pattern do the slits create? How can you change this pattern? For light, predict the locations of the fringes that appear on the screen using d sin(θ) = mλ. Use the tape measure to verify your predictions. Explain how the aperture geo...

🎓 Why Unitut Is the Future of Academic Networking — And Why You Should Be Using It Today

By Sandile MHlophe -
 In a world where attention is currency, and digital communities are shaping our habits, one platform is reimagining how students learn, connect, and even earn: Unitut . If you haven’t heard about it yet, it’s time to pay attention—because Unitut isn’t just another social app. It’s a movement that blends education, technology, and financial opportunity in a way the world has never seen before. 🚀 What Is Unitut? At its core, Unitut is a free social network designed for students, tutors, and lifelong learners . Think of it as Facebook meets a study group—with the added bonus of getting paid for your knowledge. Users can create profiles, post questions, share academic content, and collaborate across subjects and grade levels. But here’s the twist: Every time you engage—whether you’re answering questions, uploading study material, or helping another learner—you earn points . And those points? They can be withdrawn as real money . That’s right: you’re getting paid to be smart and ...
