Retreat : How the Counterculture invented Wellness
The counterculture of the Sixties and theSeventies is remembered chiefly for music, fashion, art, feminism, computing,black power, cultural revolt and the New Left.But an until-now unexplored, yet noless important aspect — both in its core identity and in terms of its ongoingsignificance and impact — is its relationship with health. In this popular and illuminating culturalhistory of the relationship between health and the counterculture, MatthewIngram connects the dots between the beats, yoga, meditation, psychedelics,psychoanalysis, Eastern philosophy, sex, and veganism, showing how the hippiesstill have a lot to teach us about our wellbeing.

Is there a timer for mindfulness training, meditation, yoga, and spirituality?
There is no set timer for mindfulness training, meditation, yoga, and spirituality as it varies from person to person. Some people may find it helpful to start with short sessions, such as 5-10 minutes, and gradually increase the duration as they become more comfortable. Others may prefer longer sessions right from the start. It's important to listen to your body and mind and find a timing that works best for you. The key is to be consistent and make it a regular practice in your daily routine.

What is the difference between standard enthalpy of formation, enthalpy of formation, and reaction enthalpy?
The standard enthalpy of formation is the enthalpy change that occurs when one mole of a compound is formed from its elements in their standard states. Enthalpy of formation is the enthalpy change that occurs when one mole of a compound is formed from its elements in their standard states, but it can be under non-standard conditions. Reaction enthalpy is the enthalpy change that occurs in a chemical reaction, which can be exothermic (heat is released) or endothermic (heat is absorbed).
-
What is enthalpy?
Enthalpy is a thermodynamic property of a system that represents the total energy of the system, including its internal energy and the energy required to maintain constant pressure. It is often denoted as H and is expressed in units of joules. Enthalpy is important in understanding and analyzing processes such as chemical reactions and phase changes, as it provides a measure of the heat content of a system. In practical terms, enthalpy change is often used to quantify the heat absorbed or released during a process at constant pressure.
-
What is the difference between bond enthalpy and formation enthalpy?
Bond enthalpy is the energy required to break a specific chemical bond in a molecule, while formation enthalpy is the energy change when one mole of a compound is formed from its elements in their standard states. Bond enthalpy is specific to a particular bond within a molecule, while formation enthalpy is a measure of the overall energy change in forming a compound. Bond enthalpy is typically measured in kilojoules per mole (kJ/mol), while formation enthalpy is also measured in kilojoules per mole (kJ/mol).

McMindfulness : How Mindfulness Became the New Capitalist Spirituality
Mindfulness is now all the rage. From celebrity endorsements to monks, neuroscientists and meditation coaches rubbing shoulders with CEOs at the World Economic Forum in Davos, it is clear that mindfulness has gone mainstream.Some have even called it a revolution. But what if, instead of changing the world, mindfulness has become a banal form of capitalist spirituality that mindlessly avoids social and political transformation, reinforcing the neoliberal status quo?In McMindfulness, Ronald Purser debunks the so-called "mindfulness revolution," exposing how corporations, schools, governments and the military have coopted it as a technique for social control andself-pacification.A lively and razor-sharp critique, Purser busts the myths its salesmen rely on, challenging the narrative that stress is self-imposed and mindfulness is the cure-all.If we are to harness the truly revolutionary potential of mindfulness, we have to cast off its neoliberal shackles, liberating mindfulness for a collective awakening.

How to calculate the reaction enthalpy from the molar bond enthalpy?
To calculate the reaction enthalpy from the molar bond enthalpy, you need to consider the difference between the sum of the bond enthalpies of the reactants and the sum of the bond enthalpies of the products. First, calculate the total bond enthalpy of all the bonds broken in the reactants, and then calculate the total bond enthalpy of all the bonds formed in the products. The reaction enthalpy is then the difference between these two values, with the bond enthalpies of the products subtracted from the bond enthalpies of the reactants. This calculation allows you to determine whether a reaction is exothermic (releasing heat) or endothermic (absorbing heat).

What is the difference between standard formation enthalpy and enthalpy change?
Standard formation enthalpy is the enthalpy change that occurs when one mole of a compound is formed from its elements in their standard states. It is a specific type of enthalpy change that is measured under standard conditions. Enthalpy change, on the other hand, is a more general term that refers to the overall change in enthalpy of a system during a chemical reaction or process, regardless of whether it involves formation of a compound or not. Enthalpy change can be positive (endothermic) or negative (exothermic), depending on whether energy is absorbed or released during the process.
-
What is Hess's law for standard formation enthalpy and combustion enthalpy?
Hess's law states that the total enthalpy change for a reaction is the same regardless of the number of steps taken to reach the final products. This principle can be applied to standard formation enthalpies and combustion enthalpies by using a series of known enthalpy changes to calculate the overall enthalpy change for a reaction. By manipulating and combining these known enthalpies, Hess's law allows us to determine the enthalpy change for reactions that may not be easily measured directly.

Is the lattice enthalpy always positive and the hydration enthalpy always negative?
The lattice enthalpy is not always positive and the hydration enthalpy is not always negative. The lattice enthalpy can be positive or negative depending on the strength of the ionic bond in a compound. For example, in some cases, the lattice enthalpy can be negative for compounds with very strong ionic bonds. Similarly, the hydration enthalpy can be positive or negative depending on the strength of the hydration of the ions in solution. For example, in some cases, the hydration enthalpy can be positive for ions that form strong interactions with water molecules.
