Einstein used E = mc^2 to prove that mass and energy are relative to each other. This lesson describes how energy can be converted into mass. "Some people when they enter a relationship focus all their energy "It might be a matter of not having as much time to do your work, "Planning for your future is important, and seeing the long term visions and goals is vital. But when it comes to our own relationships, both men and women Why doesn't age matter to some? of energy (also known as vitality) — and the extent to which they are a Photo: The success of a relationship depends on partners sharing similar values, beliefs and goals about their relationship.

Of the 10 textbooks we surveyed, 8 defined energy, and all of them included energy in the index. Only four textbooks defined matter, and five included matter in the index table 2. Three biology texts included the idea that energy can promote or cause change, and two one biology, one chemistry described energy in relation to the movement of heat.

We see several problems here. First, several words e. Furthermore, abstract terms such as work may confuse students. For example, will introductory-level students understand the work done when a concentration gradient is maintained across a cell membrane or when amino acids condense to form proteins Wood-Robinson ?

The contexts in which energy appeared in the textbook indices varied. All of the textbooks addressed various forms of energy e. In the biology textbooks' indices, there was a clear focus on movement e.

In contrast, similar discourse was not apparent in the physics and chemistry textbooks' indices. Furthermore, only two biology indices listed conservation of energy or laws of thermodynamics, whereas all of the physics and chemistry textbooks did.

But what these trends tell us is that the majority of the population is likely to partner with someone of similar age. This largely has to do with having social circles that generally include peers of similar ages and being attracted to others who are similar. Similarity entails many things, including personality, interests and values, life goals and stage of life, and physical traits age being a marker of physical appearance.

Why doesn't age matter to some? Many of the reasons proposed for age-gap couples have been largely rooted in evolutionary explanations, and focus on explaining older man-younger woman pairings. From this perspective, it's thought men's preferences for younger women and women's preferences for older men relate to reproductive fitness.

That is, the extent to which someone has "good genes" — indicated by their attractiveness and sense of energy also known as vitality — and the extent to which they are a "good investment" — indicated by their status and resources as well as their warmth and sense of trust. Although men and women place importance on a partner who is warm and trustworthy, women place more importance on the status and resources of their male partner.

This is largely because, with women being the child bearers, the investment is very high on their behalf time and effort in child bearing and rearing.

Mind the gap – does age difference in relationships matter?

So they are attuned to looking for a partner who will also invest resources into a relationship and family. But because the building of resources takes time, we tend to acquire resources later in life and so are older by the time we have acquired enough wealth and resources to comfortably provide for others.

So, women's attunement to status and resources might explain why some women may be attracted to older men. In contrast, there's evidence to suggest men value attractiveness and vitality more than women because, from an evolutionary standpoint, youth is seen as an indicator of fertility.

Given men cannot bear children, evolution suggests they're attuned to younger women to enhance the chances of partnering with someone who can provide children.

Mind the gap – does age difference in relationships matter?

But the evolutionary explanation is limited in that it doesn't explain why the reverse occurs an older woman-younger man pairingor why age gaps exist within same-sex couples. For this, socio-cultural explanations might provide insights.

With more women working, in higher positions and being paid more, they no longer have such a reliance on men for resources.

So fewer women will prioritise resources when looking for a mate. As for same-sex couples, there's very little research. Some suggest a lack ofor a reduced pool of, suitable age-similar mates may bring about same-sex coupling with large age differences.

What are the relationship outcomes for age-gap couples? Many people assume that age-gap couples fare poorly when it comes to relationship outcomes. But some studies find the relationship satisfaction reported by age-gap couples is higher. These couples also seem to report greater trust and commitment and lower jealousy than similar-age couples.
