Chemists From The United States

"The most infuriating assertion regularly made by the "trans women are biologically male" camp is that trans people are somehow "denying" or "erasing" biological sex differences, and that this hurts cisgender women/"[w:Female|biological females]].” This is patently untrue. I can assure you that trans people are highly aware of biological sex differences — the fact that many of us physically transition demonstrates that we acknowledge that sexually dimorphic traits exist and may be important to some people! I would reframe things this way: Transgender people often have a more complicated relationship with our sex-related traits (as they may be discordant with our identified and lived genders), and thus the language that we use to describe or discuss these traits may seem arcane, or nonsensical, or unnecessary to the average cisgender person. And because they are unfamiliar with this language (and/or flat-out antagonistic toward us), some cisgender people will subsequently misinterpret this language and differing perspective as some sort of "denial.""

"Like women more generally, many trans women are feminists. Feminism and transgender activism are not in any way incompatible or mutually exclusive. As feminists who acknowledge intersectionality, we believe that we should be fighting to end all forms of sexism and marginalization — this includes both traditional sexism and transphobia. Forcing trans women into a separate group that is distinct from cis women does not in any way help achieve feminism’s central goal of ending sexism."

"Claims that trans women are not women often rely on essentialist (and therefore incorrect) assumptions about biology. For instance, people might argue that trans women are not “genetically female,” despite the fact that we cannot readily ascertain anybody’s sex chromosomes. Indeed, most people have never even had their sex chromosomes examined, and those that do are sometimes surprised by the results. Other common appeals to biology center on reproduction — e.g., stating that trans women have not experienced menstruation, or cannot become pregnant. This ignores the fact that some cisgender women never menstruate and/or are unable to become pregnant. Claims about genitals are similarly problematic: Women’s genitals vary greatly, and as with chromosomes and reproductive capabilities, we cannot readily see other people’s genitals in everyday encounters. If you and I were to meet, should I refuse to recognize or refer to you as a woman unless you show me your genitals? And frankly, what could possibly be more sexist than reducing a woman to what’s between her legs? Isn’t that precisely what sexist men have been doing to women for centuries on end?"

"Trans women who are conventionally feminine are not in any way asserting or insinuating that all women should be conventionally feminine, or that femininity is all there is to being a woman. Like cis women, trans women dress the way we do in order to express ourselves, not to critique or caricature other women."

"Once a person acknowledges that they possess some form of privilege, they are more likely to accept the reality that they are not in any way objective about the form of marginalization in question"

"I mentioned at the outset that I dislike the term "identity politics." This is because the phrase seems to suggest that our identities (rather than the marginalization we face) is the most salient feature of our activism. Indeed, this is probably why those who oppose IP-umbrella activism seem so fond of calling it “identity politics” in the first place. [...] In contrast, within IP circles, the term is often reserved for a specific brand of single-issue activism that completely precludes perspectives from those who do not share the identity in question."

"While gender socialization is quite real, all of us are capable of overcoming or transcending the socialization that we experienced as children. And gender socialization doesn’t simply stop when one reaches adulthood: All of us are constantly facing gender-related social pressures, expectations, and obstacles throughout our lives. If you believe that these statements are true for cis women, then they also must be true for trans women."

"As a trans woman, I will be the first to admit that I cannot possibly know what any other woman experiences or feels on the inside. But the thing is, the trans-women-aren’t-women crowd cannot possibly know what any other woman experiences or feels either! Every woman is different. We share some overlapping experiences, but we also differ in every possible way. Every trans woman I know acknowledges this diversity. In contrast, it’s the cis women who attempt to exclude us who seem to have a singular superficial stereotypical notion of what constitutes a woman, or of what women experience."

"Trans women are women. We may not be “exactly like” cis women, but then again, cis women are not all “exactly like” one another either. But what we do share is that we all identify and move through the world as women. And because of this, we all regularly face sexism. That is what we should be focusing on and working together to challenge. And as I said at the outset, forcing trans women into a separate group that is distinct from cis women does not in any way help achieve feminism’s central goal of ending sexism. In fact, it only serves to undermine our collective cause."

"Many cissexual people seem to have a hard time accepting the idea that they too have a subconscious sex — a deep-rooted understanding of what sex their bodies should be. I suppose that when a person feels right in the sex they were born into, they are never forced to locate or question their subconscious sex, to differentiate it from their physical sex. In other words, their subconscious sex exists, but it is hidden from their view. They have a blind spot. (5 - Blind Spots: On Subconscious Sex and Gender Entitlement)"

"Trans women do not transition out of a desire to be feminine; we transition out of a self-understanding that we are or should be female (commonly referred to as gender identity)."

"...as I grew up, we spent a lot of time learning things about the world that most youngsters in cities don’t learn these days."

"I would get up and explain how things really work. That was my job."

"I don’t have any pride, I’m sorry to say. I have zero pride in any award. All I feel is obligation, obligation, and obligation."

"Be a physical chemist, an analytical chemist, an organic chemist, if you will; but above all, be a chemist."

"The structure known, but not yet accessible by synthesis, is to the chemist what the unclimbed mountain, the uncharted sea, the untilled field, the unreached planet, are to other men. The achievement of the objective in itself cannot but thrill all chemists, who even before they know the details of the journey can apprehend from their own experience the joys and elations, the disappointments and false hopes, the obstacles overcome, the frustrations subdued, which they experienced who traversed a road to the goal. The unique challenge which chemical synthesis provides for the creative imagination and the skilled hand ensures that it will endure as long as men write books, paint pictures, and fashion things which are beautiful, or practical, or both."

"Boyle entertains the hypothesis of a universal matter, the concept of atoms of different shapes and sizes, and the possibility of existence of substances that might properly be called elements... The atomic theory as originally conceived by Democritus and Epicurus, developed by Lucretius, and resurrected by Gassendi from about 1647 on, was doubtless the source from which Boyle derived his ideas, ...as he cites both Epicurus and Gassendi. Boyle, however... avoids any dogmatic assertion of these hypotheses. It is plain, however, that these atoms or "corpuscles" as he calls them are a constant element of his thought."

"After all, what's the use of having developed a science well enough to make predictions, if in the end all we're willing to do is stand around and wait for them to come true."

"Knowledge of the components of the atom and of the forces that hold them together stimulated entirely new fields of basic science and technology that continue to the present."

"The definite mass ratios involved in reactions suggested a convenient method for counting the number of atoms of each element participating in the reaction. These results, summarized as the laws of chemical combination,provided overwhelming, if indirect, evidence for the existence of atoms and molecules."

"Laboratory or industrial chemical reactions are carried out with quantities that range from milligrams to tons, so we must be able to relate the relative atomic mass scale to the macroscopic scales used in practice. The link between the two scales is provided by Avogadro’s number (NA)."

"The science of chemistry rests on two well-established principles: the conservation of matter and the conservation of energy."

"The conservation of matter in a chemical change is represented in a balanced chemical equation for that process. The study of the relationships between the numbers of reactant and product mole­cules is called stoichiometry. Stoichiometry is fundamental to all as­pects of chemistry."

"Chemists think in the highly visual nanoscopic world of atoms and molecules, but they work in the tangible world of macroscopic laboratory apparatus. These two approaches to the chemical sciences cannot be divorced."

"Investigating chemical reactions can be greatly complicated and often obscured by the presence of extraneous materials. So, the first step, therefore, is to learn how to analyze and classify materials to ensure that you are working with pure substances before initiating any reactions."

"Upon encountering a new topic, try this: imagine that you are the first person ever to see the laboratory results on which it is based. Imagine that you must construct the new concepts and explanations to interpret these results, and that you will present and defend your conclusions before the scientific community. Be suspicious. Cross-check everything. Demand independent confirmations. Always remain, with Boyle, the “skeptical chemist.”"

"Chemical reasoning, as used both in applications and in basic research, resembles a detective story in which tangible clues lead to a mental picture of events never directly witnessed by the detective."

"We point out that not every reactant is completely consumed in a chemical reaction, and that the limiting reactant determines the maximum theoretical yield; the percentage yield may be somewhat less."

"Quantum mechanics explains the physical stability of the atom by predicting its allowed discrete energy levels and defining the wave functions (also called atomic orbitals) associated with each energy level. The orbitals determine the probability density for finding the electrons at particular locations in the atom when the electrons are in a specific quantum state."

"The central idea of quantum theory is that energy, like matter, is not continuous but it exists only in discrete packets. Discreteness of matter and charge on the microscopic scale seems entirely reasonable and familiar to us, based on the modern picture of atomic structure. But, the idea that energy also exists only in discrete chunks is contrary to our experience of the macroscopic world. The motions of a soccer ball rolling up and down the sides of a gully involve arbitrary amounts of kinetic and potential energy; nothing in ordinary human experience suggests that the energy of a system should change abruptly by “jumps.” Understanding quantum mechanics requires that we develop a new kind of physical intuition, based on the results of experiments that are impossible to understand using classical mechanics. These results are completely divorced from ordinary human experience in the macroscopic world around us, and our physical intuition from the macroscopic world cannot be transferred to the quantum domain. We must resist the urge to interpret these quantum results in terms of ordinary experience."

"The shapes of molecules influence their behavior and function, especially the ease with which they can fit into various guest-host configurations important in biology and biochemistry."

"As a result, there is an electrostatic attraction between the oxygen atom of one water molecule and the hydrogen of another (Fig. 2-lb), called a hydrogen bond."

"Water is a polar solvent. It readily dissolves most bio­ molecules, which are generally charged or polar com­ pounds (Table 2-2); compounds that dissolve easily in water are hydrophilic (Greek, "water-loving"). In contrast, nonpolar solvents such as chloroform and benzene are poor solvents for polar biomolecules but easily dis­ solve those that are hydrophobic-nonpolar molecules such as lipids and waxes."

"In thermodynamic terms, formation of the solution occurs with a fa vorable free-energy change: ΔG = ΔH - TΔS, where ΔH has a small positive value and TΔS a large positive value; thus ΔG is negative."

"We can consider cellular energy conversions—like all other energy conversions—in the context of the laws of thermodynamics."

"The chemistry of living organisms is organized around carbon, which accounts for more than half the dry weight of cells."

"The current understanding that all organisms share a common evolutionary origin is based in part on this observed universality of chemical intermediates and transformations, often termed "biochemical unity.""

"Virtually every chemical reaction in a cell occurs at a significant rate only because of the presence of enzymes."

"The upper limit of cell size is probably set by the rate of diffusion of solute molecules in aqueous systems."

"All living organisms fall into one of three large groups (domains) [Bacteria, Archeara, Eukarya] that define three branches of evolution from a common progenitor."

"Cells of all kinds share certain structural features."

"The remarkable similarity of metabolic pathways and gene sequences across the phyla argues strongly that all modern organisms are derived from a common evolutionary progenitor by a series of small changes (mutations), each of which conferred a selective advantage to some organism in some ecological niche."

"The unity and diversity of organisms become apparent even at the cellular level."

"The distinguishing characteristics of eukary­otes are the nucleus and a variety of membrane-enclosed organelles with specific functions."

"Despite these common properties, and the fundamental unity of life they reveal, it is difficult to make generalizations about living organisms."

"Perhaps the most remarkable property of living cells and organisms is their ability to reproduce themselves for countless generations with nearly perfect fidelity. This continuity of inherited traits implies constancy, over millions of years, in the structure of the molecules that contain the genetic information."

"Biochemistry asks how the remarkable properties of living organisms arise from the thousands of different biomolecules."

"Organisms possess extraordinary attributes, properties that distinguish them from other collections of matter. What are these distinguishing features of living organisms?"

"Among the seminal discoveries in biology in the twentieth century were the chemical nature and the three-dimensional structure of the genetic material, deoxyribonucleic acid, DNA."

"The first living organisms on Earth doubtless arose in an aqueous environment, and the course of evolution has been shaped by the proper­ ties of the aqueous medium in which life began."
