Wearing gold pendants near the chest can assist in regulating heartbeats by absorbing excess energy and maintaining a harmonious frequency. Gold, known for its inert properties, can absorb surplus energy, creating a calming influence on the wearer. This absorption of extra energy by gold pendants is thought to aid in stabilizing heart rhythms and fostering a sense of equilibrium and well-being. The unique properties of gold are believed to interact with the body's energy field, contributing to a balanced frequency that positively influences heart rhythms.
The tradition of wearing glass bangles during pregnancy in Indian culture holds both cultural and scientific significance. Culturally, glass bangles are valued for the soothing sound they produce, believed to facilitate childbirth and shield the mother and baby from negative energies. From a scientific perspective, glass bangles act as pacifiers, absorbing positive elements from the environment and emitting them onto the wearer. The gentle and calming sound of glass bangles mirrors the tranquility of the surroundings, while also repelling negative energies and providing a sense of security.The precise frequency generated by the sound of glass bangles is crucial. Glass bangles vibrate at a specific frequency that is thought to regulate blood pressure, manage emotions, and induce a calming effect. This frequency aligns with the resonance of the glass material, interacting with both the wearer and the environment to enhance overall well-being and protection associated with wearing glass bangles during pregnancy.4uchemists

How do i start a flip classroom?
1. Determine the technology required: You will require an online platform (such as Google Classroom, Edmodo, or Schoology) to host your video lessons, as well as other materials such as documents and worksheets. If you intend to create your own video lessons, you may also need to invest in recording equipment. 2. Create your video lessons: Determine which topics you want to cover and then create your video lessons. You can create your own videos on a computer or tablet, or you can host videos created by other educators on platforms such as YouTube or Vimeo. 3. Plan activities for in-class time: For the in-class portion of the flip classroom, plan activities that encourage students to engage with the material and apply what they've learned. To help students further explore the topics, use group discussions, problem-solving activities, and projects. 4. Explain the flip classroom concept: Before you begin your first flipped lesson, explain to your students what the flip classroom is and how it works. Make it clear to them that they are responsible for watching the video lessons and participating in the in-class activities. 5. Evaluate and adjust: Take some time after each lesson to reflect on how it went. Request feedback from your students and make changes as needed to ensure that the flip classroom is meeting its objectives.
What are the advantages and disadvantages of a flip classroom?
Advantages:
1.
Increased student engagement: In a traditional classroom
setting, it can be difficult to keep students engaged in the lecture. In a
flipped classroom, students are actively involved in the learning process and
can take ownership of their learning. 2. Students can work at their own pace:
Students can work at their own pace and can replay video lessons if they need
to review something that was covered in the lesson. This can help them better
understand the material and can help them keep up with the rest of the class.
3. Less pressure on teachers: In a flipped classroom, teachers have more time
to interact with students and answer questions, rather than spending all of
their time lecturing. This can help teachers create a better learning
environment for their students. 4. Increased access to technology: Flipped
classrooms give students access to technology, which can help them learn more
effectively and efficiently.
Disadvantages: 1. Difficulty in implementation: Flipped classrooms require a
lot of preparation and planning, which can be difficult for teachers who don’t
have the resources or the time. 2. Technology issues: Technology can be unreliable
and can cause problems with flipped classrooms. 3. Lack of student motivation:
Some students may not be motivated to watch the videos or do the assignments,
which can lead to a decrease in learning. 4. Low engagement in video lessons:
Video lessons can be boring and lack the engagement of a traditional classroom
setting.
Which is the Flipped Workshop model in flip classroom?
The Flipped Workshop model is a type of Flipped Classroom model that is based on problem-based learning principles. Students in this model are assigned to conduct independent research and problem solving prior to attending class. The teacher serves as a facilitator during class, guiding students as they work in small groups to discuss and solve the problem. Students must be ready to present their findings and solutions to the class.
Which is the Flipped Video model in flip classroom ?
It is an instructional model that emphasises student-centered learning. It is predicated on the idea that students can watch instructional videos at home and then use class time for activities like discussion, problem-solving, and application. Teachers create videos that explain course material and assign them as pre-class assignments in this model. Teachers facilitate learning in the classroom through activities and discussions.
Which is the jigsaw model in flip classroom?
The Jigsaw Model is a cooperative learning strategy in which students are assigned roles and complete a task in small groups. This model is frequently used in a flipped classroom, where students are given tasks to complete before class so that class time can be spent on more interactive activities like discussion and collaboration.
What is the role of a teacher in flip classroom?
In
a flipped classroom, the teacher's role is to provide meaningful and engaging
instruction, to create an environment that encourages student collaboration and
problem-solving, and to facilitate learning in a way that maximises student
engagement and understanding. The teacher should also be prepared to provide
individualised support and feedback to each student as needed. Furthermore, the
teacher should provide students with guidance and support as they explore,
discover, and apply new knowledge and skills.
The
best flip classroom model will be determined by the students' individual learning
needs as well as the classroom's goals. The "Jigsaw" method, the
"Flipped Video" method, and the "Flipped Workshop" model
are all popular.
What is a Flip classroom?
What exactly is a flip classroom?
The
flip classroom teaching method is becoming increasingly popular around the
world. According to a National Center for Education Statistics report, over 30
countries use the flip classroom teaching method in some form.
It
is an instructional strategy and type of blended learning that flips the
traditional learning environment by delivering instructional content outside of
the classroom, frequently online. Rather than introducing new concepts in class
and then assigning homework, the teacher assigns learning activities as
homework and uses class time to work through activities and problems.

Grey Goo
It is a term used in nanotechnology
It refers to a disaster scenario in nanotechnology applications.
What is nanotechnology
We can say it is the use of matter on an atomic, molecular, and
supramolecular scale for industrial purposes,
In 1959, American physicist and Nobel laureate
Richard Feynman introduced the concept
of nanotechnology. Throughout the 1990s, significant advances in
nanotechnology, such as carbon nanotubes, were made. Nanomaterials were being
used in consumer products even in the early 2000s. Although modern
nanotechnology is relatively new, nanometer-scale materials have been used for
centuries.
Now lets come to Grey goo
Kim Eric Drexler In his book "Engines of Creation,"
proposed an intriguing possibility for nanotechnology. Drexler imagined a
future in which tiny machines known as assemblers could construct materials
molecule by molecule. Using billions of these assemblers, you could create
almost any material we can think of. The role of assemblers would be to put the
molecules together precisely and produce what we want.
How do you manage to hire so many assemblers? You start by making
a few in the lab. The assemblers are then instructed to construct other
assemblers. In turn, these new assemblers will start building more machines.
With each generation, the manufacturing rate becomes exponential, doubling.
But what if the production spirals out of control? This would
result in the grey goo scenario. Assemblers would start converting all organic
matter into more assemblers, consuming everything. The Earth would be reduced
to a lifeless mass of nanomachines.
What is positive about grey goo
The potential of
self-replicating machines. It can be used to solve energy-related problems like
producing low-cost solar power, cure fatal diseases like cancer by boosting the human
immune system, completely clean up the environment, and even allow for the
restoration of extinct species.
Because the technology's basic building blocks are at the
molecular level, the cheapness and abundance of materials would make it simple
and inexpensive to create any product, even cheap pocket supercomputers.
Many scientists believe
that building assemblers will be impossible for the foreseeable future.
Furthermore, due to the
enormous complexity involved, creating such nanobots is difficult, and given
current technological limitations, they are unlikely to be easily
created. (Drexler himself has stated that such self-replicating machines would
be unlikely to be built due to manufacturing inefficiency.)
Though Grey goo is not of concern yet, those working in nanotechnology should be aware of this.

Pressure Cooker Spill? Add few drops of oil
Pressure Cooker Spill? Add few drops of oil
The surface tension of water is higher. The surface tension of water is 72 dynes/cm, while the surface tension of oil is 30–35 dynes/cm.
This causes water to spill out of pressure cookers.
Now Swacch cookers are introduce as an alternate remedy.
Addition of few drops of oil to dhal in a pressure cooker redues the surface tension of water and prevents spill.
Addition of castor oil to dhal is beneficial as it helps in bowel movement and increases omega -3 – fatty acids
Crown Shyness- an interesting phenomenon in nature!
What is this crown shyness? It is something seen in trees. The above pictures show a clear outline between trees as if social distancing is practiced!!
When the tops of individual trees in the forest canopy avoid touching, it creates separation lines and boundaries in the sky. Crown shyness is the distinctive border that forms around trees.
Crown shyness (also known as canopy disengagement, canopy shyness, or intercrown spacing) is a phenomenon observed in some tree species in which fully stocked tree crowns do not touch each other, forming a canopy with channel-like gaps.
This crown shyness, may help trees in sharing resources and staying healthy.

Rupert's drop
Rupert's Drop
Prince
Rupert’s drops are formed by dropping hot molten glass into cold water.
This gives a drop
like tadpole shape (see the image taken from Creative common licence). The drop
has a strong head and a tail.
This develops
opposing forces of high compressive strength on the outside and high tensile
strength on the inside making the tail incredibly sensitive. Even if you
hit the bulky head portion with a hammer or a hard material it doesn’t break
nor can a bullet pierce through.But if the tail is disturbed, then the drop is
no more hard.
The drop becomes fragile when the tail is distorted. Because of those
opposing forces, a minor distortion to a drop’s tail causes the whole structure
to explode, almost at 1lakh frames /second.
These drops are also called Batavian tears
Prince Rupert's drops were discovered in the 17th century
Rupert of Bavaria presented 5 drops to Charles II of England.
These were turned over to the Royal Society for
study in 1661.

significant use: for making tempered
glass for modern smartphone screens
